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

Options

A. 1 V
B. 1.5 V
C. 2 V
D. 3 V

Answer

A

Explanation

Potential drop across 3 m long resistance wire is 6 V.
Potential drop across 50 cm
`(=0.5" m")` long resistance wire
`=(6)/(3)xx0.5=(3.0)/(3)=1V`
