Its means is the smallest potential difference can be measured
with the help of Potentiometer. Sensitivity of Potentiometer can be increased
by decreasing its potential gradient. The same can be achieved by
1.
By increasing the length of
potentiometer wire.
2.
If the potentiometer wire is
a fixed length, the potential gradient can be deceased by reducing the current
in the potentiometer wire circuit with help of rheostat.
