EN: Electrical potential energy is stored energy due to separated electric charges (electric potential difference/voltage). - A battery stores electrical potential energy and can transfer it to a circuit. - In a circuit it can transform into other forms (light, thermal, sound, motion).

中文：电势能是由于电荷分离而储存的能量（与电势差/电压有关）。 - 电池储存电势能，并可把能量传递到电路中。 - 在电路中可转化为光、热、声或机械运动等其他形式。
