Question:
A parallel plate capacitor has plate area $25.0 \mathrm{~cm}^{2}$ and a separation of $2.00 \mathrm{~mm}$ between the plates. The capacitor is connected to a battery of $12.0 \mathrm{~V}$
(a) Find the charge on the capacitor.
(b) The plate separations decreased to $1.00 \mathrm{~mm}$. Find the extra charge given by the battery to the positive plate.
Solution:
