Worked example of a parallel circuit. This is a parallel circuit in which you have to 00:00:00
calculate the following questions. The total equivalent resistance of the circuit. 00:00:05
The total current flowing through the circuit. The current flowing through each resistor. 00:00:11
The voltage or potential difference across each resistor. 00:00:18
The power supplied by the cell and the power dissipated in the circuit. 00:00:21
The data you are given is the value of the resistors in parallel and the voltage of the cell. 00:00:26
Firstly, the total equivalent resistance of the circuit. 00:00:33
It is really important you calculate it correctly, because you will use this value in the rest of the exercise. 00:00:37
I in this case, you have three resistors in parallel of 30, 90, and 180 ohms. 00:00:44
we obtain the total resistance of the circuit by grouping all the resistors in parallel together 00:00:50
remember to use calculator and that the result 0 0 5 it is the inverse of the equivalent resistase 00:00:56
we're looking for to calculate the total equivalent current we need to apply ohm's law to the 00:01:03
equivalent circuit intensity is equal to the voltage of the cell divided by the equivalent 00:01:09
resistance. The current flowing through each resistor. This is a parallel circuit so all of 00:01:15
the resistors have a voltage of 3V which is the cell voltage. We calculate each intensity with 00:01:22
the Ohm's law. We confirm that the total current is the sum of the three currents flowing through 00:01:28
each branch. As we said before the voltage or potential difference across all resistors is 00:01:33
the same and equal to 3V because resistors are in parallel. The dissipated power is the sum of 00:01:39
the power consumed by each resistor. You can calculate each power with the product of voltage 00:01:45
and intensity. We confirm that the delivered power and the power dissipated in the circuit are equal. 00:01:50
