A potentiometer wire has length `10m` and resistance `10Omega`. It is connected to battery of EMF `11` volt and internal resistance `1Omega`, then the potential gradient in the wire is

A

`10 V//m`

B

`1V//m`

C

`0.1 V//m`

D

none

Text Solution

Verified by Experts

The correct Answer is:
B
`i=11/(10+1)=1` Amp

`x=(iR)/L=1xx10/10=1V//m`
