In a resistor R, the peak power (achieved instantaneously 100 times per second for 50 Hz AC) is V m2 /R = i m2 *R. As discussed above, the voltage, current and so the power pass through zero volts 100 times per second, so the average power is less than this. The average is exactly as shown above: P = V m2 /2R = V 2 /R.

NettetIn a three-phase power system, The potential difference between the two phases is called line voltage (typically phase to phase). It is denoted by V L-L .
