1
00:00:00.000 --> 00:00:05.392
A simple resistor. For an ohmic resistor at a stable temperature,

2
00:00:05.392 --> 00:00:08.333
voltage equals current multiplied by resistance.

3
00:00:08.733 --> 00:00:16.298
Use the units. A 5-volt source across 1000 ohms gives 0.005

4
00:00:16.298 --> 00:00:18.361
amperes: 5 milliamperes.

5
00:00:18.761 --> 00:00:24.088
Change resistance. Double the resistance while keeping voltage fixed. The current

6
00:00:24.088 --> 00:00:26.025
becomes half as large.

7
00:00:26.425 --> 00:00:32.241
Check the model. Real parts have limits. Calculate resistor power too:

8
00:00:32.241 --> 00:00:35.942
voltage times current. Use low-voltage learning circuits.
