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 R3burns out in the series and parallel circuit?

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

Explanation / Answer

(a) if R2 burns out

R1 would be lit at same brightness but R3 would be brighter

(b) If R1 burns out

It is a an open circuit. No current will be flowing through R2 and R3. Bulbs will not glow at all

(c) if R3 burns out

R1 would be lit at same brightness but R2 would be brighter
