Q. 1

Find the equivalent resistance (Req) of given circuit network across voltage source. Draw and label the circuit diagram of each step, otherwise you will lose your marks.

Q. 2

A 12V battery is connected to a circuit containing 2 resistors and a fan having 2Ω resistance.

- Calculate the source current Is.
- Determine the voltages V1, V2, and V3.
- Calculate the power dissipated by each resistor.
- Determine the power delivered by the source, and compare it to the sum of the power levels of part (4)
