How Capacitors Work
The plate on the capacitor that attaches to the positive terminal of the battery loses electrons to the battery. Once it''s charged, the capacitor has the same voltage as the battery (1.5 volts on the battery means 1.5 volts on the capacitor). For a small capacitor, the capacity is small. But large capacitors can hold quite a charge.

The expression in Equation ref{8.10} for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors.
