The diagram shows identical lamps X and Y connected in series with a battery. The lamps light with normal brightness. |
If a third lamp Z is connected in parallel with lamp X, then what will happens to the brightness of the lamp V? |
A) Brighter than normal
B) Normal
C) Dimmer than normal
D) Very dim (cannot be seen)
Correct Answer: A
Solution :
The third lamp Z is connected parallel to X, so the current gets divided among X and Z. So both bulbs X and Z light dimmer and the bulb Y lights brighter than earlier because current through it increases.You need to login to perform this action.
