Consider the current flow of electricity within an electrical circuit. The formula of Ohm's Law says that when electric current is flowing through a resistor, the current i (measured in amps) can be calculated from the voltage v (measured in volts) and the resistance R of the resistor (measured in ohms) Complete Part (a) and Part (b) using the given formula: Part (a). The resistor in a radio circuit was measured to be 6000 ohms. 1. What is the formula for the current i in the radio circuit? Use lower-case letter v for voltage IL. Select the graph of your formula for i versus v. 25 25 1.5 15 05 05 1000 2000 3000 4000 5000 6000 7000 1000 2000 3000 4000 5000 6000 7000 OGraph 1 Oraph 2 2.5 2.5 1.5 1.5 0.5 0.5 1000 2000 3000 4000 5000 6000 7000 1000 2000 3000 4000 5000 6000 7000 OGraph 3 OGraph 4 III. What happens to the current when voltage increases? O As the resistance increases, so does the current. O As the voitage increases, so does the resistance. O As the voltage increases, so does the current. Part (b). The lights for a car operate on a 12 volt battery. I. What is the formula for the current i in the car lights? Use a capital letter R for Resistance. IL. Select the graph of your formula for i versus R. 2.5 25 2 1.5 1.5 0.5 05 10 15 20 10 15 20 OGraph 1 OGraph 2 25 25 2 2 1.5 1.5 0.5 0.5- 10 15 20 10 15 20 25 OGraph 3 OGraph 4 III. What happens to the current when resistance increases? O As resistance increases, the current increases. O As resistance increases, the current decreases O As voltage increases, the curent decreases.
