Paul Gonzales Inst: Zhang Date: January 29, 2011 BME 311 Network Theory Homework #1 Due: February 2, 2011 1. Reading assignment Fundamentals of Electric Circuits (3rd Ed), Alexander and Sadiku Chapter 1, 2 2. Basic Problems (30 points) Solve the following three problems from the textbook 1.5, 1.8 and 1.22 1.5) Determine the total charge transferred over time interval of 0=<t=<10 s when i(t) = 1/2t A Q = i × dt = 0 10 ò 1 2 t × dt = 0 10 ò t 2 4 é ë ê ù û ú 0 10 = 25 C 1.8) The current flowing past a pt. in a device is shown in Fig. 1.25. Calculate the total charge through the point. Q = (10 x 1)/2 + (10 x 1) = 15 µC 1.22) A lightning bolt strikes an airplane with 30 kA for 2 ms. How many coulombs of charge are deposited on the plane? Q = i*t = 30 x 1000 x (2 x .001) = 60 C 3. Comprehensive Problem (20 points) Solve the following problem from the textbook: 1.35 1.35) The graph represents the power drawn by an industrial plant between 8 – 8:30 AM. Calculate the total energy in MWh consumed by the plant. [ (5x5) + (4x5) + (3x5) + (8x5) + (4x10) ]/ 60 = 2.333 MWhr 4. Pspice and Matlab preparations (I) Pspice set up and basic components: Download PSpice from the following website and set it up on your computer. http://www.engr.uky.edu/~cathey/pspice061301.html 1.
