WebThe reactive power Q in volt-amps reactive (VAR) is equal to the voltage V in volts (V) times the current I in amps (A) time the sine of the complex power phase angle (φ): Q (VAR) = V (V) × I (A) × sin φ. The power factor (FP) is equal to the absolute value of the cosine of the complex power phase angle (φ): PF = cos φ Energy & power ... WebThe rated power of a average size water heater is around 4000 watt or 4 kW. But its rated power vary from 1 kW to 15 kW depending on the size and the amount of hot water it can provide in short amount of time.
