NAME PHYS-1200 PHYSICS II QUIZ 1 SEPTEMBER 25, 2002 SOLUTIONS PART A. 1. C 5. B 2. C 6. D 3. B 7. E 4. C 8. E PART B . 1. a) RIGHT (The resistance of the parallel combination of R 2 and R 3 is smaller than the resistance of R 2 alone, so more current will flow.) b) LEFT (Since less current flows through R 1 in the left circuit, there is a smaller potential drop across it, and consequently, a larger potential drop across R 2 .) c) LESS THAN THE CURRENT THROUGH R 1 (The sum of the currents through R 2 and R 3 must equal the current through R 1 .) 2. a) NEGATIVE (The net current through the path of integration is to the right, so the average direction of the magnetic field is opposite to the direction of integration.) b) The magnitude of s B d = μ 0 (2.0 A) c) POSITIVE (The direction of integration about each wire is in the same direction as the magnetic field produced by that wire.) d) The magnitude of s B d = 0 (4.0 A)
