Question

what is Potentiometer?
define its and its formula​

Answer 1

Answer:

potentiometer is the meter in which we can read the scale of the temperature

Answer 2

A potentiometer consists of a long wire with uniform area of cross section which is made up of manganin or constantan. Potential gradient (K) is the potential drop per unit length. It is calculated as V/L, where V is the potential difference between two points and L is the distance between two points...

Potentiometer is a device used to measure the internal resistance of a cell, to compare the e.m.f. of two cells and potential difference across a resistor. It consists of a long wire of uniform cross sectional area and of 10 m in length..
