A 12-volt battery is connected to two light bulbs, as drawn in Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2 has resistance 6 ohms. The battery has essentially no internal resistance, and all the wires are essentially resistanceless, too. When a light bulb is unscrewed, no current flows through that branch of the circuit. For instance, if light bulb 2 is unscrewed, current flows only around the lower loop of the circuit, which consists of...

5. When a light bulb is connected to a 4.5 V battery, a current of 0.16A passes through the bulb filament. What is the resistance of the filament? What is the power delivered to the light bulb? (5pts)
Use a 50 V battery in series with a switch, connected to a 10 Ω resistor R1 and a light bulb with resistance R2 = 100 Ω in parallel. Use a current chart to monitor the current through the bulb and a voltage chart to monitor the voltage across the switch. Make predictions before you play the animation: Before you close the switch, predict the voltage across the switch and the current through the bulb. Record your prediction. After you...
