How can we justify?

Generally the capacitor equ is C=Q/V. Then how?

Prasanna said: (Jul 6, 2011)  
Q=CV is the correct answer.

The amount of charge raised or decrease by voltage. It is electrical charge stored element.

Capacitors are used to store charge. The amount of charge raised or decrease by voltage. That's why there is a direct relation between charge and voltage. And the equation below best describes the relation.

Q=CV.

Charge stored in a capacitor is directly proportional to the the voltage applied across it. So Q is directly proportional to V. And C is the proportionality constant so the answer is Q=CV.

The charge in the capacitor is raised and reduced by the amount of voltage applied. So the charge is directly proportional to the voltage.

Mahinder Singh said: (Nov 12, 2013)  
We donate capacitance charge to Q and donate capacitor voltage to the Cv and the answer is Q=Cv.

We donate capacitance charge to Q and donate capacitor voltage to the Cv and the answer is Q=Cv.

It should be Q = CV^2.

Well said @anmoypramanik.
