Name:______________________________________________ EE 313 – Homework Assignment 4 Total Points: 20 Fall 2008 Score:_______ Due Thursday, October 23 rd 1. Find the load impedance, Z L, such that the load absorbs maximum average power. What is this maximum average power? 2. A voltage source serves the following loads, which are all connected in parallel: Load 1 – 20kVAR at PF=.4 lagging Load 2 – 10 50˚ kVA Load 3 – 6kW at PF = 1 The magnitude of the source voltage is 250 volts rms and the system operates at 60 Hz.
