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 close the switch, predict the voltage across the switch and the current through the bulb. Record your prediction.
