how can sensitivity of potentiometer be increased

Sensitivity of potentiometer means the degree of response whenever there is a change in the input signal. It depends upon the following factors:

1. Resistance of the wire,

2. Number of turns in the wire. More the number of turns more sensitivity of the potentiometer.

3. Increasing the length of the wire.

The potential gradient depends upon resistsnce nd no of turns not d sensitivity. The sensitivity varies inversely with potential gradient and can b increased by 1)increase in the length of the wire as potential gradient =dv/dl so as l increases the potential gradient decreases . 2)by decreasing the current as I is directly proportional to V so as I decreases V also decreases hence potential gradient decreases.

The sensitiveness of a potentiometer can be increased in the following ways-
1. Increasing length of potentiometer wire
2. Decrease the potential gradient by reducing the current and increasing the resistance in the potentiometer wire using a rheostat.

Hope it helps.

Sensitivity of potentiometer can be increased by increasing the length of the potentiometer wire and by reducing the current in the circuit by using a rheostat. Both the methods help in decreasing the potential gradient, and thereby increasing the resistivity.

I hope, it'll be helpful to you!

This can be done by 2 ways. i) Increasing the length of the potentiometer wire and ii) Adding a series resistance with the potentiometer due to which current in it would decrease.

The principle of a potentiometer is.
When a steady current passes thru a wire of uniform cross-sectional area, the potential difference across the portion of the wire is directly proportional to the length of the portion.

V=IR => V=(I.rho.l)/A  => V is directly proportional to l. 
 V/l=potential gradient
 To increase the sensitivity, increase the potential difference and decrease the length...

The sensitivity of the potentiometer depends upon the value of potential gradient K. (K=Potential supplied by main battery divided by length of wire) Smaller the value of K, smaller the potential difference that a potentiometer can measure and more is the sensitivity of the potentiometer. Thus, for a given potential difference, the sensitivity of the potentiometer increases with the increase in length of potentiometer wire.
