If the value of potential gradient on potentiometer wire is decreased, then the new null point will be obtained at

The potential gradient of the potentiometer wire depends on

Potential gradient of a potentiometer is equal to

What is the unit of potential-gradient ? If the potential gradient along the potentiometer wire be decreased, will the zero-deflection position be obtained at longer length or shorter length ?

The potential gradient for a potentiometer depends on

The potential gradient for a potentiometer depends on

If the length of the potentiometer wire is doubled, the sensitivity for obtaining null point will –

If potential gradient of a wire decreases, then its length

If the length of potentiometer wire is increased, then the accuracy in the determination of null point

If the length of potentiometer wire is increased, then the accuracy in the determination of null point

A cell of negligible internal resistance is connected to a potentiometer wire and potential gradient is found. Keeping the length as constant, if the radius of potentiometer wire is increased four times, the potential gradient will become (no series resistance in primary)
