Question

A network has two branches in parallel. One branch contains impedance Za and the other branch has impedance Zb. If it is fed from an AC voltage V of frequency f, the current through Za depends, on which of the following?

(a) V, Za, Zb

(b) V, Za

(c) Za, Zb

(d) V, Za, f

I got this question in class test.

My question is taken from Advanced Problems on Application of Laplace Transform in division Application of the Laplace Transform in Circuit Analysis of Network Theory

Answer 1

Correct choice is (d) V, Za, f

The explanation: We know that, in parallel branches, the current through any branch depends only on V (voltage), Z (impedance) and f (frequency) only.

So, the current through Za depends on V, Za, and f.
