Solution

In this circuit, 8Ω and 12Ω are connected in parallel, and this parallel resistors are connected in series with 7.2Ω.

8Ω and 12Ω are in parallel, their equivalent resistance:

1R=18+112=524

R=4.8Ω

Now, Equivalent resistance (series connection) of the circuit =4.8+7.2=12Ω

V=IReq

I=VReq=612=0.5A

Potential Difference across 7.2Ω resistor =I×R=0.5×7.2=3.6V
