Question

if length of a potentiometer wire is increased by keeping constant potential difference across the wire then​

Answer 1

Answer:

the rate of flow of electricity will increase

Answer 2

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

Explanation:

• The null point is disturbed and obtained at larger distance than earlier.
• The potential gradient is the rate at which a potential changes with position in a specified direction.
• This  potential gradient is equal to V/L i.e., Potential difference divided by length of the wire.
• Thus the Potential gradient is inversely proportional to the length and the directly proportional to the potential difference.

• Also the null point is obtained at longer distance.
