If the length of a potentiometer wire is increased by keeping constant potential difference across the wire, then

The sensitivity of potentiometer wire can be increased by

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 potentiometer wire carries current. The potential difference across 70 cm of its balances the potential difference across a 2 ohm coil supllied by a cell of e.m.f. 2 volt. When a 1 ohm coil is placed in parallel with the 2 ohm coil, a length equal to 50 cm of the potentiometer wire is required to balance the potential difference across the parallel combination. What is the internal resistance of the 2 V cell?

The length of a potentiometer wire is 10m and a potential difference of 2 volt is applied to its ends. If the length of its wire is increased by 1m, the value of potential gradient in volt/m will be (potential difference across potentiometer wire remain same)

The length of a potentiometer wire is 10m and a potential difference of 2 volt is applied to its ends. If the length of its wire is increased by 1m, the value of potential gradient in volt/m will be (potential difference across potentiometer wire remain same)

Length of potentiometer wire is 600 cm and a driving cell develop 6V potential difference across it. The potential gradient along the wire is?

If the radius of a potentiometer wire is increased four times, keeping its length constant, then the value of its potential gradient will become
