Question

The charge on capacitor C2 in the circuit shown below is?

(a) 0

(b) 1

(c) 2

(d) 3

This question was posed to me in an online interview.

My question is taken from The Impulse Function in Circuit Analysis topic in section Application of the Laplace Transform in Circuit Analysis of Network Theory

Answer 1

Correct choice is (a) 0

The best explanation: In the circuit, the initial charge on C2 is zero. So, charge on capacitor C2 = zero. Capacitor circuit and series inductor circuit are two different cicuits to illustrate how an impulse function can be created with a switching operation.
