Networks Analysis and Synthesis

Q1:
In figure, the switch is closed at t = 0. After some time i = 6A and rate of change of current was 4A/s. The value of inductor is

A 1 H

B 1.5 H

C indeterminate

D 0.5 H

ANS:D - 0.5 H

Steady state current = A. Therefore, i = (1 - e-3t/L) = 6A and From these equations L = 0.5H.
