Question

1. Consider the following if you set up the circuits in the lab using light bulbs as your resistors. Would the bulbs continue to be lit for the following conditions? If so, would they be brighter (draw more current) or dimmer (draw less current)?

a)Light bulb R2 burns out in the series circuit?

b)Light bulb R1 burns out in the parallel circuit?

c)Then light bulb R3 burns out in the parallel circuit?

d)Light bulb R3 burns out in the series and parallel circuit?

e) Then Light bulb R1 burns out in the series and parallel circuit?

Explanation / Answer

a)
When R2 burns out, circuit will be broken and current will not flow
In this case Bulb will no longer lit

b)
When R1 burns out, more current will flow through bulb and it will get brighter

c)
When R3 burns out, more current will flow through bulb and it will get brighter

d)
When R3 burns out, circuit will be broken and current will not flow
In this case Bulb will no longer lit

e)
When R1 burns out, circuit will be broken and current will not flow
In this case Bulb will no longer lit
