Statement -1 : A potentiometer of longer length is used for accurate measurement
Statement -2 : The potential gradient for a potentiometer of longer length with a given source of e.m.f becomes small

Assertion: A potentiometer of longer length is used for accurate measurement Reason: The potential gradient for a potentiometer of longer length with a given source of e.m.f becomes small

Assertion : A potentiometer of longer length is used fof accrurate measurement. Reason : The potential gradient for a potentiometer of longer length with a given source of e.m.f. becomes small.

Why do we prefer potentiometer of longer length for sensitive measurements?

A current of 1.0 mA is flowing through a potentiometer wire of length 4 m and of resistance 4 Omega , find the potential gradient of potentiometer wire

Assertion : Electric field outside the conducting wire accurate measurement. Reason : The potential gradient for a potentiometer of accurate measurement. Reason : Net charge on conducting wire is zero.

A potentiometer consists of a wire of length 4 m and resistance 10Omega . It is connected to a cell of emf 2V.The potential gradient of the wire is
