PROBLEM – 01

In the circuit given in figure, find the value of R and the current flowing through it, if current through branch OA is zero.

PROBLEM – 02

In the circuit shown in figure, use mesh analysis to find out the power delivered to the 4Ω resistor. To what voltage should the 100 V battery should be changed so that no power is delivered to the 4Ω resistor?

PROBLEM – 03

In the circuit shown in figure, find the voltage across A & B.

PROBLEM – 04

Calculate the current supplied by the batteries and the potential difference between A & B.

PROBLEM – 05
