ECE 211 Fall 2009 Circuit Analysis I Project 1 (due W, 30-Sep-09, at the beginning of lecture) Objective To learn the basics of MATLAB while solving some basic circuits. Required Output For each problem, you should submit a printout of the MATLAB code, with values of input and output variables listed. Box each answer and indicate which part (a, b, c, etc.) it corresponds to. P1. In the circuit shown to the right, a battery is driving a DC motor. The motor voltage V m is related to the motor speed and is 0.27V/RPM [i.e., 0.27 volts for each RPM (revolution per minute) the motor turns]. The motor speed is 36 RPM. Use V b = 28V, R b = 0.6Ω, and R m = 0.2Ω. (a) What is the motor current I m ? (b) What is motor terminal voltage V t ? (c) What is the power supplied to the motor ( R m and V m )? (d) How much of the power from part (c) is dissipated in the motor and how much is converted to mechanical energy? ( Hint: R m dissipates power; V m doesn’t.) You must use MATLAB to answer these questions, as described below. First define each of your parameters. For instance, after typing the first line, your code might look like this: >> Rb = .6 Rb = 0.6000 >> where the symbol >> is your MATLAB
