Description:

In this video I will find power-factor=? of a 3-phase motor consuming 4.8kW when the line voltage is 220V and the line current is 15.4A. This will require using the triangle representing the real power, P; the reactive power, Q; and the complex (apparent) power, S. And the relationship where the complex power, S, is a function of the line-voltage and line-current.
