Problems-5
Using superposition theorem, calculate the current through the Î© impedance branch of the circuit shown in the figure below.

Solution
Case I. 30 V source is acting alone

Impedance,

âˆ´

Case II. 20 V source is acting alone

Impedance,

âˆ´

By superposition theorem, total current flowing through the  impedance is,
