The diagram shows identical lamps X and ...

The diagram shows identical lamps X and Y connected in series with a battery. The lamps light with normal brightness. If a third identical lamp Z is connected in parallel with lamp X, then what wiII happen to the brightness of lamp Y?

A

Brighter than normal

B

Normal

C

Dimmer than normal

D

Very dim (cannot be seen)

Text Solution

Verified by Experts

The correct Answer is:
A
Lamps X and Y are connected in series with a battery. If a third identical lamp Z is connected in parallel with X, then resistance of whole circuit reduces. Due to this, current drawn from battery will increase and bulb Y will be brighter than normal.
