Question

Determine the voltage across the capacitor in the circuit shown below is?

(a) VC = 60(1-e^-t)V

(b) VC = 60(1+e^t)V

(c) VC = 60(1-e^t)V

(d) VC = 60(1+e^-t)V

This question was posed to me in examination.

I'm obligated to ask this question of DC Response of an R-C Circuit topic in section Transients of Network Theory

Answer 1

Right choice is (a) VC = 60(1-e^-t)V

To explain: The expression of voltage across capacitor in the circuit VC = V(1-e^-t/RC) = 20(1-e^-t)V.
