Question

A potentiometer consists of a wite of length 4 meter and registamce 10 ohm. It is connected to a cell of emf 2v the potential gradient will be

Answer 1

Hey mate!!

Potential gradient

X= V(ab)/L

X= 2/4

X= 0.5V/m

Answer 2

Potential gradient is given by :

Voltage / length .

Given :

voltage= 2 v

length = 4 m

Gradient = 2 v / 4 m

               = 1 / 2 v/m

               = 0.5 v/m

The gradient is 0.5 v/m
