In a series parallel circuit, you have to use the specific characteristics of series or parallel
00:00:00
in each branch of the circuit. In the circuit, you can see here there is a resistor in series
00:00:06
with two that are in parallel. Firstly, calculate the equivalent resistance.
00:00:12
You calculate the resistors that are in parallel and then add the one that is in series.
00:00:19
The second question is the total current, remember is always the voltage of the cell
00:00:24
divided by the equivalent resistance. In this exercise they are asking for the currents trough
00:00:30
each resistor, the resistor 1 is in series with the cell, so the intensity is the same that in
00:00:37
the circuit. But this intensity is divide between the two resistors in parallel. The voltage here
00:00:43
is not the voltage of the cell. You can calculate it because the voltage is the difference between
00:00:51
the voltage of the cell and the voltage of the resistor 1. Other way to calculate the intensities
00:00:57
is through the divisor of intensities. It is a proportion between the equivalent resistance in
00:01:03
the parallel branch and the resistance of each of the parallel resistors. You decide with way is easier.
