Question

What is galvanometer and its function

Answer 1

˙·٠•●♥

Galvanometer, instrument for measuring a small electrical current or a function of the current by deflection of a moving coil. The deflection is a mechanical rotation derived from forces resulting from the current. ♥●•٠·˙

Answer 2

Galvanometer is an instrument used to measure current through the circuit

Explanation:

• Galvanometer is an instrument which works on the deflection of moving coil placed in permanent magnetic field. It is used to measure electric current through the given circuit, its zero lies at center so can measure current having any direction that is can measure current even if the connections of galvanometer are made wrong
• Galvanometer can be converted into large range of ammeter by connecting a low value resistance that is shunt in parallel to the galvanometer

• Galvanometer can be converted into voltmeter by connecting a high value resistance connected in series to the galvanometer
