Multiple-choice questions may continue on the next column or page – fnd all choices beFore answering. 001 (part 1 oF 2) 10.0 points A battery with an emF oF 13 V and internal resistance oF 0 . 43 Ω is connected across a load resistor R . IF the current in the circuit is 2 . 16 A, what is the value oF R ? Answer in units oF Ω. 002 (part 2 oF 2) 10.0 points What power is dissipated in the internal re- sistance oF the battery? Answer in units oF W. 003 (part 1 oF 2) 10.0 points ±our resistors are connected as shown in the fgure. 92 V S 1 c d a b 17 Ω 42 Ω 52 Ω 82 Ω ±ind the resistance between points a and b . Answer in units oF Ω. 004 (part 2 oF 2) 10.0 points What is the current in the 42 Ω resistor? Answer in units oF A. 005 10.0 points The Following diagram shows a closed elec- trical circuit. The ammeter in the center oF the resistive network reads zero amperes. E S 1 A 4 Ω 6 Ω R x ±ind the electric resistance R X . 1. R X = 9 Ω . 2. R X = 12 Ω . 3. R X = 21 Ω . 4. R X = 18 Ω . 5. R X = 4 Ω . 6. R X = 7 Ω . 7. R X = 24 Ω . 8. R X = 14 Ω . 9. R X = 5 Ω . 10. R X = 17 Ω . 006 (part 1 oF 3) 10.0 points Consider a circuit with three identical bulbs, an ideal battery, and a switch S . Assume the resistance oF each light bulb remains constant. V i 1 i 2 i 3 S A B C i 0 Leaving S open, compare i 0 , i 1 , and i 2 .
