Question

what is potentiometer and how we convert it into galvanometer and then into ammeter​

Answer 1

Answer:

Explanation:

potentiometer :

A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

how we convert it into galvanometer and then into ammeter :

A galvanometer can detect only small currents. Thus, to measure large currents it is converted into an ammeter. It can be converted into an ammeter by connecting a low resistance called shunt resistance in parallel to the galvanometer.

A potentiometer is a three-terminal resistor with a sliding or rotating

contact that forms an adjustable

voltage divider. If only two terminals

are used, one end and the wiper, it acts as a variable resistor or rheostat.

how we convert it into galvanometer and then into ammeter:-

As Galvanometer can only detect small currents. Thus, to measure large currents it is converted into an ammeter. It can be converted into an ammeter by connecting a low resistance called shunt resistance in parallel to the galvanometer.
