A 6 V battery is connected to the terminals of a 3 m long wire of uniform thickness and resistance of `100 Omega`. The difference of potential between two points on the wire separated by a distance of 50 cm will be

A

`1.5` volt

B

3 volt

C

3 volt

D

1 volt

Text Solution

Verified by Experts

The correct Answer is:
D
` R alpha l`
For 300 cm, `R= 100 Omega`
For `50 cm, R. = (100)/(300) xx 50= (50)/(3) Omega`
`therefore IR= 6`
`rArr IR. = (6)/( R) xx R. = (6)/(100) xx (50)/(3) = 1` volt.
