This is exercise 2 from block 8. We have a circuit with three resistors in parallel.

1
00:00:07,000 --> 00:00:13,000
Remember this is the formula for the equivalent resistance in this case. Substitute the values of

2
00:00:13,000 --> 00:00:18,000
the resistors. Use your calculator. You will need to calculate the inverse of the figure you have

3
00:00:18,000 --> 00:00:24,000
obtained. Don't forget the units. In this case you have calculated it in kilo ohms but perhaps

4
00:00:24,000 --> 00:00:31,000
is a good idea to convert it into ohms. The total intensity is the proportion between voltage of

5
00:00:31,000 --> 00:00:36,000
the cell and the equivalent resistance you calculated before. It is a parallel circuit.

6
00:00:36,000 --> 00:00:43,000
All resistors have the same voltage, the voltage of the cell. In this exercise they didn't ask

7
00:00:43,000 --> 00:00:47,000
but the intensity can be calculated with the ohms law applied into every resistor.

8
00:00:47,000 --> 00:00:53,000
Note that the addition of them should be the total intensity.
