Fall 2009 EE40 Homework #5 Due Oct 8 (Thursday), 12:00 noon in Cory 240 This is a relatively short assignment Reading Assignments Chapter 5 and Appendix A of Hambley textbook Problem 1: Phasor Practice Hambley P5.22 Consider the phasors shown below. The frequency of each signal is f =200Hz. Write a time domain expression for each voltage in the form Vmcos(ωt+θ). State the phase relationships between each pair of these phasors. Problem 2 : Phasor diagram Hambley 5.25 Supposed that v1(t)= 100cos(ωt+45o) and v2(t)= 150cos(ωt+60o) . Use phasors to reduce the sum vs(t)= v1(t) + v2(t) to a single term of the form Vmcos(ωt+θ). Draw a phasor diagram showing V1,V2,and Vs. State the phase relationships between each pair of these phasors. Problem 3 Simple Complex Impedance Hambley P5.43 Find the complex impedance of the network shown for ω=500. Repeat for ω= 1000 and 2000.Problem 4 Nodal analysis with phasors Hambley P.5.54 Solve for the node voltage V1
