Physics 21 Fall, 2004 Practice Exam #1 1 2 3 4 5 Total Name: Recitation Section Recitation Leader Sept. 17, 2004 This exam is closed notes and closed book. You must show enough work on all problems to convince the grader you understand how to solve the problem. You may use a calculator, but you must show a full solution to simultaneous algebraic equations. An equation sheet is on the last page. There are five problems; each counts 20 points. Problem 1. 3 2 4 13 V 4 V 8 V I 1 I 3 I 2 a b (a) Write the loop and node equations needed to de- termine the currents I 1 , I 2 , and I 3 in the circuit shown. (b) Determine the currents by explicit solution of the equations. (c) Determine the value of the potential difference be- tween point a and point b ( V b V a ) in the above circuit along the path through the 4 V battery and the 2 Ω resistor.
