Solution:  QUESTION: 2

Solution:
QUESTION: 3

### For the parallel RLC circuit to be underdamped

Solution:

Characteristic equation of a parallel RLC circuit is  QUESTION: 4

For the circuit shown below, the switch K is closed at t = 0, The value of the current and their derivatives for the above circuit at t = 0 were foundout and matched as given below: Which of the above are correctly matched ?

Solution:

At t = 0+, inductor will act as open circuit therefore, i(0+) = 0 A.
Applying KVL in the loop, we have   QUESTION: 5

The energy in a network in Laplace domain is given by ​The initial and final values of power are respectively

Solution:

We know that,  QUESTION: 6

A voltage is given by The value of V(t→ ∞) is

Solution:  QUESTION: 7

The voltage across a capacitor is given by If the capacitor has the value of 2 F, initial value of current through it (at t = 0+) will be

Solution:   Hence, initial value of current through the capacitor = 2 A.

QUESTION: 8

The impedance Z(s) in the circuit shown below is Solution:

The given circuit in Laplace domain is shown below.  QUESTION: 9

The voltage Vc1,Vc2 and Vc3 across the capacitors in the circuit shown below under steady-state, are respectively Solution:

Under steady state condition inductors will act as short circuit while capacitors will act as open circuit.   QUESTION: 10
