00:00:01.480 --> 00:00:21.420
[unclear opening audio]

2
00:00:29.600 --> 00:00:35.320
And some say you can still hear the blue smoke monster

3
00:00:35.320 --> 00:00:37.380
howling in the night.

4
00:00:38.520 --> 00:00:41.540
Ooh! Spooky story.

5
00:00:41.900 --> 00:00:44.860
Very spooky, Mho. Thank you for sharing it.

6
00:00:45.320 --> 00:00:50.000
Hey, how about we lighten the mood a little bit with some music?

7
00:00:50.000 --> 00:00:51.660
I brought my guitar here.

8
00:00:51.820 --> 00:00:53.700
Well, I've been working on a little song.

9
00:00:54.160 --> 00:00:58.000
Have either of you heard of the scientist Georg Simon Ohm?

10
00:00:58.400 --> 00:00:59.420
I haven't.

11
00:00:59.560 --> 00:00:59.860
No.

12
00:01:00.640 --> 00:01:01.280
Fantastic.

13
00:01:02.140 --> 00:01:04.400
Adabot, throw me a G chord, please.

14
00:01:04.780 --> 00:01:05.260
Will do.

15
00:01:09.940 --> 00:01:10.620
Yeah.

16
00:01:12.720 --> 00:01:15.320
Georg Simon Ohm was experimenting,

17
00:01:15.880 --> 00:01:18.880
and he happened upon something very interesting.

18
00:01:18.880 --> 00:01:23.840
He found that volts and currents are related to each other, but it's not like

19
00:01:23.840 --> 00:01:26.160
they're cousins or sisters or brothers.

20
00:01:26.480 --> 00:01:30.520
It's a rule that we now call Ohm's Law.

21
00:01:31.680 --> 00:01:37.260
You can't break Ohm's Law because it's always true.

22
00:01:39.820 --> 00:01:43.980
To find one value, you only need the other two.

23
00:01:46.300 --> 00:01:50.300
Say you're working in a circuit and you need a certain current

24
00:01:50.300 --> 00:01:53.520
10 milliamps from a 9-volt supply

25
00:01:53.520 --> 00:01:57.000
How many ohms will give you those amps?

26
00:01:57.280 --> 00:02:00.540
You don't have to guess or take any chances

27
00:02:00.540 --> 00:02:04.880
Just apply and rely on Ohm's law

28
00:02:05.940 --> 00:02:08.320
You can't break Ohm's law

29
00:02:09.440 --> 00:02:11.480
Because it's always true

30
00:02:13.800 --> 00:02:18.320
Find one value, you only need the other two

31
00:02:21.480 --> 00:02:27.140
Divide voltage by current to find the resistance

32
00:02:28.480 --> 00:02:33.920
Resistance times current will tell you the volts

33
00:02:34.480 --> 00:02:40.880
Divide voltage by resistance to find the current

34
00:02:40.880 --> 00:02:41.540
Nice.

35
00:02:41.720 --> 00:02:45.900
And that's all that we call Ohm's Law.

36
00:02:45.940 --> 00:02:46.160
Wow.

37
00:02:47.480 --> 00:02:49.940
So, you really can't break Ohm's Law?

38
00:02:51.020 --> 00:02:52.020
No, you can't.

39
00:02:52.040 --> 00:02:53.360
Like, not even sometimes?

40
00:02:53.380 --> 00:02:54.520
It is always true.

41
00:02:55.100 --> 00:02:58.260
And to find one of the values, I just need the other two.

42
00:02:58.360 --> 00:02:59.060
You've got it!

43
00:03:01.000 --> 00:03:06.440
You can't break Ohm's Law, because it's always true.

44
00:03:08.880 --> 00:03:13.260
To find one value, you only need the other two.

45
00:03:47.120 --> 00:03:48.040
We'll see you next time.
