Problem 4 The circuit in Figure 5 is comprised of four resistors, each labeled according to the amount of resistance it presents. The battery in the circuit maintains a voltage of AV. A. Write an expression for the current that is moving through each resistor. I now connect points A and B with a wire and light bulb in the middle, as shown in Figure 6. B. When I connect points A and B with the wire, does the bulb light up? Use power P = 1'V as part of your description and justifica- tion. C. Write expressions for the current through the resistors 2R and 4R with the wire between A and B present. 2R 4R Figure 5: A four resistor circuit with battery of voltage AV. 2R 4R Figure 6: A four resistor circuit with battery of voltage AV, connecting points A and B with a wire and light bulb
