Difference Between Ammeter and Galvanometer

The major significant difference between ammeter and galvanometer is that ammeter shows only magnitude of current whereas galvanometer shows both the direction and magnitude of current.

Difference Between Ammeter and Galvanometer

The galvanometer deflects the flow of current with the help of a moving coil which rotates between the permanent magnets and with the flow of current, deflection of the coil occurs. A galvanometer can be turned into an ammeter by parallely connecting a resistance in the electric circuit. It can be used as a voltmeter when resistance is connected in series with it.

Ammeter is used to measure the magnitude of current. It is also called as ampere meter because ampere is the unit of current.
