Period 15 Exercises: Resistance and Power Write answers to the questions below. Show your mathematical steps and the units of the quantities. This sheet with your answers should be turned in at the beginning of Period 16. 1 . Relating resistance and voltage: k, Six 1.5 volt batteries in series are connected in series to a 15 cm resistor wire and a. 30 cm resistor wire. We assume that the connecting wires have no resistance. a) What is the total voltage boost from the batteries? b) How much of a voltage drop is across the 15 cm wire? c) How much of a voltage drop is across the 30 cm wire? 2. Using Ohm's Law: A 1,350 watt heater operates from a 120 volt outlet. What is the resistance of this heater?
