September 13, 2011 EE 335 – Electromechanical Energy Conversion and Energy Systems Fall Semester 2011 – Dr. Jignesh Solanki Homework#2 Solution Due: Tuesday, September 13 Problem 1: A circuit consists of two impedances, Z1 = 20∠30 0 Ω and Z2 = 14.14∠-45 0 Ω, in parallel, supplied by a source voltage V = 100∠60 0 volts. Determine the power triangle for each of the impedances and for the source. (ref. 2.20) Problem 2: A single phase source has a terminal voltage V = 120∠0 0 volts and a current I = 25∠30 0 A, which leaves the positive terminal of the source. Determine the real and reactive power, state whether the source is delivering or absorbing each. (ref. 2.23)
