Question

Note: Use principles of physics to solve the problem and thenverifyyour answer using the simulation.

Before pressing any buttons in the simulation, predict whatthecircuit will do.

(a) When the circuit is turned on (andtheswitch is open), predict how the bulbs will compare in termsoftheir brightness. For this situation, which of thefollowingstatements are true? Select all that apply.

1

Bulb A will be brighter than bulbB. Bulb A will be dimmer than bulbB.Bulbs A and B will be equallybright. Bulb A will be brighter thanbulbC. Bulb A will be dimmer than bulb C.Bulbs A and C will beequallybright. Bulb B will be brighter than bulbC. Bulb B will bedimmer than bulb C.Bulbs B and C will be equallybright.

(b) With the circuit stillturned on, what will happen to thebrightness of each bulb when theswitch is closed? Select all thecorrect statements from the listbelow.

2

The brightness of bulb A willincrease. The brightness of bulb Awilldecrease. The brightness of bulb A will remain thesame. Thebrightness of bulb B willincrease. The brightness of bulb Bwilldecrease. The brightness of bulb B will remain thesame. Thebrightness of bulb C willincrease. The brightness of bulb Cwilldecrease. The brightness of bulb C will remain thesame.
