Learn Electronics/Capacitors
Capacitors can be thought of as temporary sources of voltage. Assume that a capacitor is rated at 10 volts, then, to charge it, any voltage up to 10 V can be supplied to its terminals, possibly directly, or via a series resistance. Many capacitors require proper polarity (direction of applied voltage), otherwise damage could be the result.
