Why Galvanometer Cannot Be Used to Measure Current?

The galvanometer is a very sensitive device. Hence, it may get damaged when a strong current is passed through the galvanometer. ... The galvanometer resistance is larger than the ammeter, if it is connected in series it will reduce the current flow through the circuit.

Can a galvanometer be used to measure current?

No, a galvanometer as such can not be used for measuring current as it is a very sensitive instrument as it shos full scale deflection even for a very small current.

Why we Cannot use galvanometer as an ammeter?

A galvanometer shows a full scale deflection with a very small current. Hence a galvanometer can measure limited current. Therefore as such, a galvanometer can not be used as an ammeter, which can measure the given large current.
