Sensitivity of potentiometer can be increased by

Question

Sensitivity of potentiometer can be increased by (A) increasing the e.m.f. of the cell (B) increasing the length of the potentiometer wire (C) decreasing the length of the potentiometer wire (D) none of the above

Tardigrade Admin · Accepted Answer

The sensitivity of potentiometer can be increased by decreasing gradient, i.e., by increasing the length of potentiometer wire. (Sensitivity propto (1/ textPotential gradient) propto Length)

Q. Sensitivity of potentiometer can be increased by

increasing the e.m.f. of the cell

increasing the length of the potentiometer wire

decreasing the length of the potentiometer wire

none of the above

The sensitivity of potentiometer can be increased by decreasing gradient, i.e., by increasing the length of potentiometer wire.
(Sensitivity $\propto \frac{1}{Potential gradient} \propto$ Length)
