Power: A. The product of applied voltage (potential difference) and current in a direct-current circuit (or the voltage squared divided by the resistance, or the current squared times the resistance). B. The product of the effective values of the voltage and current with the cosine of the phase angle (between current and voltage) in an alternating-current circuit. C.Power The amount of energy (in joules) that a device delivers or consumes divided by the time (in seconds) that the device is operating. See: apparent power and rms power.
