Question

potential difference between two points of a wire carrying 2 ampere current is 0.1 volt calculate the resistance between these points

Answer 1

potential difference=0.1V
I=2A
R=?
R=V/I
V stands for potential difference
R=0.1/2
R=1/20
R=0.05 omega

Answer 2

Resitance of a conductor is the opposition to the flow of charge. It depends on the length of the conductor, its area of cross section and the resistivity of the material. Its unit is Ohms.

It can also be calculated as

R=V/I

Where

1. R= resistance
2. V= potential difference
3. I= Current

In this case

R=0.1 V ÷ 2 A

R= 0.05 Ω
