One plate of a parallel-plate capacitor is smaller than the other. Then the charge on the smaller plate will be

1. Less than the other
2. More than the other
3. Equal to the other
4. Will depend upon the medium between them

Correct answer: Equal to the other

Solution

A capacitor stores equal and opposite charges on its two plates. The difference in plate size may affect surface charge density, but not the total charge on each plate. Therefore, the smaller plate carries charge equal in magnitude to the other plate.
