How do you convert a galvanometer to an ammeter?

A galvanometer is an instrument used to measure and detect electric currents. While that seems a lot similar to an ammeter, it only deals with measuring relatively small or mediocre currents. Although an ammeter is now much preferred due to its more accurate, faster, and advanced readings, there is a way to "convert" a galvanometer to function like an ammeter. A current separator or divider, known as a shunt, allows a simple meter to be calibrated (adjusted) to measure larger currents. The shunt, parallel to the coil of your galvanometer, allows more electric currents to circulate around the circuit, thus obtaining more current.


What is the principle of galvanometer?

Galvometer works on the principle of conversion of electrical energy into mechanical energy. It is an instrument used to indicate the presence, direction or strength of a small electric current.


What is used to turn the pointer of a galvanometer?

A small current passes through the coil that actuates the pointer. When you select different ranges on the instrument you are in fact selecting different resistors so that the sensitivity of the pointer is changed.


What is a eletroscope?

An electroscope is an early scientific instrument. It is used to detect and measure electricity or an electric charge on a body.
