41.
The time constant of the circuit in figure shown.
RC
Answer: Option
Explanation:
Time constant 
Req.C
when V is shorted and R is seen from C then Req = R || R = R/2
.
42.
In the circuit shown in given figure, the values of i(0+) and I(∞), will be respectively
Answer: Option
Explanation:
I(t) = 6 e-t - 3 e-0.5t
at t = 0, I(0) = 3A
at t = ∞, I(∞) = 0.
