Is the current almost the same in all the wires?---------------------- Calculate the resistance of Bulb 1 (R1), resistance of Bulb 2 (Rz), resistance of Bulb 3 (R3), and the total resistance connected to the battery. Calculate the power for each bulb. 5. What happens to the brightness of the bulbs as you add more bulbs in series? 6. What happens to the overall resistance connected to the battery as you add more bulbs in series? 7. What happens to the current through the battery as you add more bulbs in series? When nished, remove circuits 2 and 3 (select each item, right click, then remove). Keep circuit 1. Light Bulbs in Parallel 1. Set up a second circuit with one battery and two bulbs in parallel as shown below. This is circuit 2. Use the voltmeter and the non-contact ammeter to measure the values listed below. Circuit 2.
