A wire of resistance `4 Omega` is stretched to twice its original length. The resistance of stretched wire would be

A

`2Omega`

B

`4Omega`

C

`8Omega`

D

`16Omega`

Text Solution

Verified by Experts

The correct Answer is:
D
As the resistance of stretched wire `R'=n^(2)R=2^(2)xx4`
`= 4xx4=16 Omega`
