Electrical and Electronic Engineering (EEE) : Capacitors - Quiz(MCQ)
For high frequencies, capacitor acts as ________
A)
Amplifier
B)
Rectifier
C)
Short circuit
D)
Open circuit

Correct Answer : Option (C) :   Short circuit


Explanation : Capacitive impedance is inversely proportional to frequency. Hence at very high frequencies, the impedance is almost equal to zero, hence it acts as a short circuit and there is no voltage across it.
