In a parallel-plate capacitor, one plate has a smaller area than the other. How does the charge on the smaller plate compare to the charge on the larger plate?

1. The smaller plate holds less charge
2. The smaller plate holds more charge
3. Both plates hold equal charge
4. It depends on the medium between the plates

Correct answer: Both plates hold equal charge

Solution

In an ideal capacitor, the two plates acquire equal and opposite charges. The difference in plate area does not change the magnitude of charge on each plate.
