Power =
(amount of work done, energy transferred, or energy dissipated, in some length of time)
divided by
(the length of time)
Power factor is defined as the ratio of real power over total power. Total power is the vector sum of real and reactive power.
Electrical power = current x voltage Current is in amps
Power is energy divided by time, P=E/t.
The formula is: current (in amps) = power (in watts) , divided by (240 times the power factor). The power factor is 1 for incandescent light or heaters, otherwise it can be assumed to be 0.75 for other loads.
