Networks Analysis and Synthesis - Engineering

Q1:

A circuit has two branches in parallel and each branch has only one element. The applied voltage and source current are v = 200 sin (200t + 30°) and i = 50 sin (200t + 50°). If one branch has capacitor, the other branch contains

A resistance

B inductance

C capacitance

D resistance or capacitance

ANS:A - resistance

The current is leading the voltage. Therefore, it is an RC circuit.
