`n` identical light bulbs, each designed to draw `P` power from a certain voltage supply , are joined in series across that supply. The total power which they will draw is

A

`nP`

B

`P`

C

`P/n`

D

`P/(n^2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`1/(P') + 1/P + 1/P + …n-"bulbs"`
`P' = P//n`.
