4. How does the net charge on a charged capacitor differ from the net charge on an uncharged capacitor? OA OB The net charge on the charged capacitor is greater than on the uncharged capacitor. There is a net charge on the charged capacitor, but there is no net charge on the uncharged capacitor. The charged capacitor has a greater positive charge than the uncharged capacitor. The net charge on both capacitors is the same. OC OD

ANSWER

The net charge on both capacitors is the same

EXPLANATION

The net charge of a capacitor is the sum of the individual charges of each plate of the capacitor.

On a charged capacitor, both plates have the same amount of charge - but opposite. Therefore, the net charge is zero.

On an uncharged capacitor each plate has zero charge, so the net charge is also zero.

Hence, the net charge is always the same: zero.
