Question

The capacitor doesn’t allow sudden changes in  ___________

(a) Voltage

(b) Current

(c) Resistance

(d) Capacitance

I got this question during an interview.

This interesting question is from Inductor and Capacitor in chapter Inductance, Capacitance, and Mutual Inductance of Electric Circuits

Answer 1

Correct option is (a) Voltage

To explain I would say: Any small change in voltage occurs within zero time across the gives an infinite current which is practically impossible. So, in a fixed capacitor, the voltage cannot change abruptly.
