Will a dielectric-filled capacitor store...

Will a dielectric-filled capacitor store more charge or less charge than a similar air capacitor at the same potential difference?

Text Solution

Verified by Experts

More charge, because the capacitance of a dielectric-filled capacitor is larger than that of an air filled capacitor, and Q = CV.
