Define potential gradient.

Obtain the dimension of potential gradient.

A 2 volt battery, a 15 Omega resistor and a potentiometer of 100 cm length, all are connected in series. If the resistance resistance of potentiometer wire is 5 Omega , then the potential gradient of the potentiometer wire is

State the S.I. unit of potential gradient.

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

Answer the following question: Define potential difference.
