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.
