COMPLEX NOTATION FOR POWER IN AC - EXAMPLE 2

This tutorial walks through a practical AC power analysis problem. We calculate total current, real power, apparent power, and power factor for a combined load (induction motor, heater, fluorescent lamps) connected to a 240V, 50Hz supply. The video emphasizes the critical process of breaking down given apparent power (kVA) into its real (P) and reactive (Q) components before summing loads in parallel to find the correct output values.
