b) when S is off
R = 100 + 50 = 150
I = V/R = 0.06 A
when S is on
R = 150/2 = 75
I = 0.12 A
c) Power, for S is OFF = VI = 0.54 W
Power, S on = 1.08 W

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.
