Question

What is the load current in terms of source current in the shunt equalizer?

(a) Is jX1/(Ro+jX1)

(b) Is jX1/(Ro+2jX1)

(c) Is jX1/(2Ro+2jX1)

(d) Is jX1/(2Ro+jX1)

The question was posed to me by my college director while I was bunking the class.

The question is from Shunt Equalizer topic in section Filters and Attenuators of Network Theory

Answer 1

The correct answer is (d) Is jX1/(2Ro+jX1)

The explanation: The load current in terms of source current in the shunt equalizer is Il = Is (jX1/2)/(Ro+jX1/2)). On solving, Il= Is jX1/(2Ro+jX1).
