Question 2

For the below given electrical network, the switch S1 is closed at t = -2 sec. Calculate I1 at t = – 1.5 sec given that u(t) is the unit step signal.

Question 3

Consider the following circuit

The value of at t = 0+ will be _______ .

Question 4

For t <0 consider the circuit 1.

Fig: Circuit 1

At t = 0, The current suddenly drops to 0A.

If t1 is the time in μsec, that makes

: Where Vc (0) = capacitor voltage at initial condition.

The value of t1 in μ sec is ___
