Can you express the potential gradient in terms of specific resistance of the wire ? If yes, find the relation.

Specific resistance of a wire depends upon

Specific resistance of a wire depends on its

Specific resistance of a wire depends on its

The specific resistance of a wire will depend on:

What do you mean by potential gradient?

The expression for potential gradent of potentiometer wire in terms of specific resistance p of the wire area of its cross -section A and current I flowing wire is……..

The resistance of a wire can be expressed in the unit.

Calculate the potential gradient of a potentiometer wire of length 5 m ,if resistance of the wire is 5 Omega and current of 1.2 mA flows through it.

A potentiometer has uniform potential gradient. The specific resistance of the material of the potentiometer wire is 10^(-7) ohm-metre and the current passing through it is 0.1 ampere, cross-section of the wire is 10^(-6)" m"^(2) . The potential gradient along the potentiometer wire is
