Gonzalez California State Polytechnic University, Pomona Department of Electrical and Computer Engineering Homework 4 Due : Tuesday, March 19, 2019 by 4:00 PM. 1. ( Root-Mean-Square ) Given the signal shown in Figure 1 : (a) Find the rms value of the periodic voltage signal. (b) If this voltage is applied to the terminals of a 4 Ω resistor, what is the average power dissipated in the resistor? v i ( t ) [ V ] t [ s] 10 20 - 10 - 20 0 25 50 75 100 125 150 175 200 Figure 1 2. ( Complex Power ) Find the impedance, complex power, apparent power, average power, reactive power, and power factor of the load connected to the source in the circuit shown in Figure 2 . Let v s ( t ) = 353 . 5534 cos(2 π 60 t ) V. - + v s ( t ) 9 F C 20 Ω R 1 115 mH L 60 Ω R 2 Figure 2 1

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
