A:
5 A/s
B: 
C:
20 A/s
D:

Answer: A
A two-port network is represented by ABCD parameters given by
If port is terminated by RL, then input impedance seen at port 1 is given by
If port is terminated by RL, then input impedance seen at port 1 is given by
A: 
B: 
C: 
D: 
Answer: D
From transmission matrix
V1 = AV2 - BI2 
I/P impedance 
I1 = CV2 - DI2
Given V2 = - I2.R1
.
In the network of the figure is the maximum power is delivered to RL if its value is
Answer: B
max power will be transfer, when RL is equal to internal resistance of voltage source then 
.
An RC circuit initially at rest has a step signal. The response V(t) across C is V(t) = 1 - e-at, If now there is an initial voltage on C of 2 volts for the same step signal, V(t) is now
Answer: A
At t = 0+, V0 = 4 volt.
at t = ∞ C open Vf = 4 x 2 = 8 volt.
