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)?

1A. Light bulb R2 burns out in the series circuit?

1B. Light bulb R1 burns out in the parallel circuit?

1C. Then light bulb R3 burns out in the parallel circuit?

1d)   Light bulb R3 burns out in the series and parallel circuit?

1e. Then Light bulb R1 burns out in the series and parallel circuit?

Explanation / Answer

Here,

1A) if R2 burns out in series connection

the circuit will break

bulbs will go dark.

1B)

oif R1 burns out in parallel connection

the potential across other bulbs will be same

and all bulbs glow with same brightness

1C)

if R3 burns out in parallel connection

the potential across other bulbs will be same

and all bulbs glow with same brightness

1D)

if R3 burns out in series and parallel connection

the circuit will break

bulbs will go dark.
