单词	electric power
释义	electric power The rate of expending energy or doing work in an electrical system. For a direct-current circuit, it is given by the product of the current passing through a system and the potential difference across it. In alternating-current circuits, the power is given by VIcosφ, where V and I are the RMS values and φ is the phase angle. Cosφ is called the power factor of the circuit
