Welcome to this English lesson about electricity.
1
1570
3440
00:05
Now, I should tell you,
2
5010
1110
00:06
I did do a lesson earlier this year about electricity.
3
6120
3970
00:10
I'll put a link right there, if you want to check it out,
4
10090
2570
00:12
but in that lesson, I was in my classroom,
5
12660
2966
00:15
and in order to teach you words and phrases
6
15626
2984
00:18
about electricity in English,
7
18610
1530
00:20
I simply held up pictures.
8
20140
2100
00:22
Now, when you learn a language,
9
22240
1460
00:23
it's always good to review things,
10
23700
1850
00:25
so I thought today we would review the topic electricity,
11
25550
4410
00:29
but I would do it in a way where I show you
12
29960
2270
00:32
as many things as I can,
13
32230
2040
00:34
and I demonstrate as many things as I can,
14
34270
2960
00:37
as I teach you English words and phrases
15
37230
2890
00:40
that you'll need to know to talk about electricity.
16
40120
2876
00:42
(cheerful music)
17
42996
2750
00:49
Well, hey, welcome to this English lesson about electricity.
18
49650
3520
00:53
Before we get started, though, if you are new here,
19
53170
2230
00:55
don't forget to click that red subscribe button over there
20
55400
3150
00:58
and give me a thumbs up if this video helps you
21
58550
2400
01:00
learn just a little bit more English.
22
60950
1830
01:02
Well, let's talk about electricity.
23
62780
2350
01:05
One of the first things I want to talk about
24
65130
2710
01:07
is how electricity is generated, or how power is generated.
25
67840
4980
01:12
We use the word electricity and power
26
72820
3130
01:15
interchangeably in English.
27
75950
2160
01:18
Behind me, you can see a wind turbine.
28
78110
2880
01:20
This wind turbine is generating electricity.
29
80990
3130
01:24
It is generating power.
30
84120
2050
01:26
It is using the energy in the wind to turn the blades
31
86170
4260
01:30
so that it can turn a generator and create electricity.
32
90430
3860
01:34
This is not a windmill.
33
94290
1810
01:36
A windmill is something else.
34
96100
1570
01:37
I'll put a picture here,
35
97670
1200
01:38
so that you can see what a windmill is,
36
98870
1940
01:40
but one way that we generate electricity,
37
100810
3140
01:43
one way that we generate power is by using a wind turbine.
38
103950
4600
01:48
Another way to generate electricity is to use solar panels.
39
108550
3480
01:52
You can see this farm behind me has a bull (laughs)
40
112030
3300
01:55
and a solar panel installation,
41
115330
1870
01:57
so they are using the power of the sun
42
117200
2720
01:59
to generate electricity.
43
119920
1550
02:01
You can also see in the distance
44
121470
1780
02:03
that this building has some solar panels on it as well.
45
123250
3750
02:07
If this was a bigger installation,
46
127000
2740
02:09
if they had more solar panels,
47
129740
1550
02:11
we would call it a solar farm.
48
131290
2000
02:13
I'm happy that I was able to show you
49
133290
1980
02:15
an actual wind turbine,
50
135270
1760
02:17
and I'm happy that I was able to show you
51
137030
2290
02:19
a solar panel installation,
52
139320
1980
02:21
but I can't show you all of the other kinds of power plants
53
141300
4060
02:25
because they don't exist out here in the country,
54
145360
2810
02:28
but I will talk about them,
55
148170
1340
02:29
and I will put pictures here while I do.
56
149510
2230
02:31
We have nuclear power plants,
57
151740
2480
02:34
where we use the power of the splitting of an atom
58
154220
3340
02:37
in order to create heat,
59
157560
1610
02:39
and we use that heat to generate electricity.
60
159170
2450
02:41
We have coal-fired power plants,
61
161620
2330
02:43
where we burn coal to create heat,
62
163950
2460
02:46
and we use that heat to create electricity.
63
166410
2760
02:49
We have natural gas-fired power plants,
64
169170
2863
02:52
where we burn natural gas
65
172033
1917
02:53
and we use the heat that is generated to create electricity,
66
173950
3600
02:57
and in Canada, we have hydro-electric power plants,
67
177550
3620
03:01
where we use the power of flowing water
68
181170
2440
03:03
to create electricity.
69
183610
1420
03:05
This behind me is not a power plant.
70
185030
2930
03:07
It is simply a power station,
71
187960
2500
03:10
or what we sometimes call a power substation,
72
190460
3200
03:13
where high-voltage electricity comes in
73
193660
3430
03:17
with the power lines on one side,
74
197090
2600
03:19
and I think a different voltage goes out,
75
199690
2760
03:22
a more usable voltage goes out on the other side,
76
202450
3280
03:25
that can be sent to homes and business.
77
205730
2930
03:28
So once the power is generated at the power plant,
78
208660
3170
03:31
it needs to get to everyone's homes.
79
211830
2640
03:34
Behind me you see what we would call a utility pole
80
214470
3680
03:38
or a telephone pole,
81
218150
1380
03:39
and in this part of Canada, we call this a hydro pole,
82
219530
3620
03:43
and at the top, you will see the power lines.
83
223150
3090
03:46
That is what we use to get the electricity
84
226240
3320
03:49
from the power plant to someone's home
85
229560
2360
03:51
or to their place of business.
86
231920
2150
03:54
So I'm not sure if you can see this,
87
234070
2130
03:56
but there are power lines over there along the road,
88
236200
3810
04:00
and then there are power lines that come onto my property.
89
240010
3800
04:03
Up here on this pole, you see a transformer,
90
243810
3620
04:07
which takes the electricity,
91
247430
2300
04:09
takes the power that's coming in
92
249730
1880
04:11
from power lines on the road
93
251610
2080
04:13
and changes the voltage to be more usable
94
253690
2720
04:16
for us here on the farm.
95
256410
1790
04:18
The first place that electricity
96
258200
1770
04:19
actually comes into a building at our place
97
259970
2560
04:22
is in the barn,
98
262530
1100
04:23
and the first thing it goes through is a meter.
99
263630
3110
04:26
This meter measures how much electricity we are using,
100
266740
4480
04:31
so that at the end of each month,
101
271220
1850
04:33
the power company knows how much they need to charge us.
102
273070
4010
04:37
So this meter measure how much electricity we are using.
103
277080
4020
04:41
After the electricity goes to the meter,
104
281100
2580
04:43
it goes to what we call an electrical panel
105
283680
3250
04:46
or a breaker box.
106
286930
1660
04:48
Inside here are circuit breakers
107
288590
2940
04:51
and each circuit breaker
108
291530
1360
04:52
is for a different circuit in the barn.
109
292890
2610
04:55
We have another electrical panel in the house,
110
295500
3090
04:58
and it contains circuit breakers
111
298590
1890
05:00
for every electrical circuit that we have in the house.
112
300480
3890
05:04
This is a roll of electrical wire.
113
304370
2200
05:06
This is the wire that runs through the walls of our house.
114
306570
4830
05:11
So I just showed you the breaker box
115
311400
2730
05:14
or the electrical panel.
116
314130
1620
05:15
From the electrical panel, there is electrical wire
117
315750
3760
05:19
that runs through the walls of the house
118
319510
1990
05:21
to all of the light switches and to all of the outlets.
119
321500
3250
05:24
If you are building a home in Canada,
120
324750
2000
05:26
you will install electrical boxes
121
326750
2810
05:29
in the places where you need outlets
122
329560
2410
05:31
and in the places where you need light switches.
123
331970
2460
05:34
An electrical outlet in Canada looks like this.
124
334430
4150
05:38
We use 120 volts as our voltage in Canada,
125
338580
4550
05:43
and this is a typical outlet that you would see
126
343130
2460
05:45
in a Canadian home, also in an American home,
127
345590
3180
05:48
and of course, to make it look nice,
128
348770
1980
05:50
we would put a plate on the front when we are all done.
129
350750
2780
05:53
So you would see these outlets in Canadian homes
130
353530
3390
05:56
or American homes,
131
356920
950
05:57
and that's what we call them in English.
132
357870
1750
05:59
We say that is an electrical outlet,
133
359620
2030
06:01
or we just say an outlet.
134
361650
1580
06:03
Of course, in some places,
135
363230
1950
06:05
you will want to install light switches
136
365180
2480
06:07
in the electrical box,
137
367660
1800
06:09
and you will want to put a nice plate on the front as well,
138
369460
3100
06:12
and then you could use this box to turn off your lights
139
372560
3050
06:15
or to turn on your lights.
140
375610
1613
06:18
This is a light fixture.
141
378310
3390
06:21
You would put this on a ceiling and connect wires to it,
142
381700
3470
06:25
and you would screw in a light bulb into the light socket,
143
385170
4070
06:29
so that this light fixture would then work,
144
389240
2520
06:31
and of course,
145
391760
833
06:32
these wires would go back to the light switch.
146
392593
3797
06:36
So there you go.
147
396390
1300
06:37
A little introduction to what light switches,
148
397690
2850
06:40
what electrical outlets, and what light fixtures look like
149
400540
3030
06:43
in a Canadian home and in American home.
150
403570
2910
06:46
Electricity is really cool, and it powers a lot of things.
151
406480
4350
06:50
This is a small heater here.
152
410830
2190
06:53
This is how we refer to this part of any device
153
413020
4570
06:57
that uses electricity.
154
417590
1690
06:59
This is the cord for that device, and this is the plug.
155
419280
4350
07:03
In order for this to work, I need to plug it into an outlet.
156
423630
4040
07:07
So that's how you talk about anything that you are using
157
427670
4020
07:11
that needs electricity.
158
431690
1530
07:13
You have a cord and you have a plug,
159
433220
2680
07:15
so if you could just pretend
160
435900
2410
07:18
that we are in the house right now,
161
438310
1720
07:20
I am going to plug in this heater.
162
440030
2340
07:22
I am going to plug it in to this outlet.
163
442370
2713
07:26
There.
164
446770
833
07:27
It's not gonna work because,
165
447603
947
07:28
you know, there's nothing on the back.
166
448550
1880
07:30
If I needed to put this heater far away from the outlet,
167
450430
4480
07:34
I would need to use what we call an extension cord.
168
454910
4140
07:39
So an extension cord is a really long cord
169
459050
3920
07:42
that you plug into the outlet on one end,
170
462970
3060
07:46
and then it has on the other end,
171
466030
2560
07:48
a spot where you can plug in whatever you are using.
172
468590
3620
07:52
And if you needed to plug in more than one thing,
173
472210
2440
07:54
you could use a power bar.
174
474650
1770
07:56
So I can plug this power bar into this extension cord,
175
476420
5000
08:01
and then I can plug these cords (laughs)
176
481540
5000
08:06
into the power bar.
177
486700
2130
08:08
One second here.
178
488830
1060
08:09
I have too many cords here.
179
489890
2290
08:12
So there you go.
180
492180
910
08:13
When you need to plug in more than one thing,
181
493090
2460
08:15
you can use a power bar.
182
495550
1940
08:17
When you are plugging something in,
183
497490
1930
08:19
you want to make sure that you don't touch
184
499420
2530
08:21
these metal prongs on the plug.
185
501950
2430
08:24
Also, you don't want to touch any bare wire,
186
504380
3720
08:28
if the cord is frayed,
187
508100
2040
08:30
because you can get electrocuted.
188
510140
2110
08:32
When you get electrocuted,
189
512250
1250
08:33
it means that the electric current enters your body
190
513500
3380
08:36
and it will injure you.
191
516880
1290
08:38
Electricity is actually very, very dangerous.
192
518170
3640
08:41
Of course, if you're far from an outlet
193
521810
1910
08:43
and you're using something small, like a radio,
194
523720
2950
08:46
that can run off of batteries,
195
526670
1750
08:48
you can always put batteries into it.
196
528420
2410
08:50
This is what we call a AA battery.
197
530830
2590
08:53
This is a AAA battery,
198
533420
2140
08:55
and this is a 9-volt battery.
199
535560
2290
08:57
So if you're using something small
200
537850
2220
09:00
that runs off of batteries,
201
540070
1570
09:01
you can always put batteries in it.

Sometimes, when you are using a computer,
203
543570

09:05
you need to use one of these,
204
545560
1350
09:06
which actually has a few names in English.
205

Sometimes we call it a power supply,
206
549340
2480
09:11
sometimes we call it a charger,
207
551820
1920
09:13
and sometimes we call it an adaptor.
208

You're probably safe to use any of those three words
209
555630

09:19
and people will know what you are talking about.

So I don't know a lot about vehicles,
211
561770
1850
09:23
but I do know there is a 12-volt battery
212
563620
2620
09:26
in every vehicle in Canada and in the United States,
213
566240
3300
09:29
and that battery is used to start the vehicle.
214
569540
3070
09:32
There is also an alternator in every vehicle,
215
572610
2950
09:35
and that alternator turns when the engine is running
216
575560
3480
09:39
and creates about 13.5 volts of electricity
217
579040
4300
09:43
to charge the battery
218
583340
1470
09:44
and to run all of the electronic components in the vehicle.
