A 4microF capacitor is charged to 120V, the charge in the capacitor would be?

Electrical and Electronic Engineering (EEE) : Capacitors - Quiz(MCQ)

30C

480C

30microC

480microC

Correct Answer : Option (D) : 480microC

Explanation : Q is directly proportional to V. The constant of proportionality in this case is C, that is, the capacitance. Hence Q=CV.
Q=4*120=480microC.
