In an RC series circuit, when the switch is closed and the circuit is complete, what is the response?

(a) Response does not vary with time

(b) Decays with time

(c) Increases with time

(d) First increases, then decrease

This question was addressed to me at a job interview.

This interesting question is from Transients in CR Networks topic in division Capacitance and Capacitors of Basic Electrical Engineering

Best answer
Right answer is (b) Decays with time

For explanation: In an RC series circuit, the response decays with time because according to the equation, there is an exponential decrease in the response.
