Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A 19 V battery delivers 120 mA of current when connected to a 78 Ω resistor. Determine the internal resistance of the battery. Answer in units of Ω. 002 (part 1 of 2) 10.0 points A string of 24 identical Christmas tree lights are connected in series to a 120 V source. The string dissipates 65 W. What is the equivalent resistance of the light string? Answer in units of Ω. 003 (part 2 of 2) 10.0 points What is the resistance of a single light? Answer in units of Ω. 004 10.0 points Consider the circuit shown in the figure. 25 V 30 Ω 1 Ω 46 Ω 13 Ω 16 Ω Find its equivalent resistance. Answer in units of Ω. 005 10.0 points A resistor with an unknown resistance is con- nected in parallel to a 17 Ω resistor. When both resistors are connected in parallel to an emf source of 18 V, the current across the un- known resistor is measured with an ammeter to be 3 A. What is the resistance of the unknown re- sistor? Answer in units of Ω. 006 (part 1 of 2) 10.0 points The power supplied to the circuit shown in the figure is 14.0 W....
