Question

what is potentiometer?​

Answer 1

Answer:

an instrument for measuring an electromotive force by balancing it against the potential difference produced by passing a known current through a known variable resistance.

Explanation:

A potentiometer (also known as a pot or potmeter) is defined as a 3 terminal variable resistor in which the resistance is manually varied to control the flow of electric current. A potentiometer acts as an adjustable voltage divider.

Answer 2

Potentiometer :-

An instrument for determining a potential difference or electromotive force by measuring the fraction of it that balances a standard electromotive force.

I hope you got it
