Question

Write short note on sensitivity of potentiometer.. ​

Answer 1

Answer:

it depends on the length of the wire

Explanation:

because potential gradient is inversely proportional to length of the given wire

Answer 2

Answer:

Sensitivity is the ability of a potentiometer to measure even a small change in potential difference. A potentiometer is said to be sensitive if it can measure very small potential difference. Smaller the potential difference it can measure, greater is its sensitivity.

Explanation:

Sensitivity of potentiometer means the smallest potential difference that can be measured by using it and this can be achieved by decreasing the potential gradient by increasing the length of the wire or reducing the current in the potentiometer using rheostat.
