A : The potentiometer wire should have uniform cross sectional area.
R : On the pottentiometer wire the jockey is gently tocuhed , not pressed hard.

Why should the potentiometer wire be of uniform cross-section and composition ?

Why should the potentionmeter wire be of uniform cross-section and composition?

Why should the area of cross section of metre bridge wire be uniform?

A current of 0.01 A flows through a potentiometer wire of cross section area 10^(-6)m^(2) . If the specific resistance of the potentiometer wire is 10^(-7) ohm-m, then the potential gradient will be

In the following circuit, resistance of potentiometer wire is 100 Omega . Power consumption in potentiometer wire is same when jockey is placed at 10 cm from end A or end B. Internal resistance of cell (r ) is
