A battery of 6 volts is connected ot the termainals of a three meter long wire of uniform thickness and resistance of the order of `100 Omega`. The difference of potential between two points separated by `50 cm` on the wire will

A

1 V

B

1.5 V

C

2 V

D

3 V

Text Solution

Verified by Experts

The correct Answer is:
A
`l_(1) = 3m = 300 cm, l_(2) = 50 cm`
`I = 6/100 = 0.06 A`
`R_(50) = (50/300) xx 100 = 50/3 Omega`
`V_(50) = 0.06 xx 50/3 = 1V`
`rArr V_(2) = 1V`
