Ammeter
The meter uses for measuring the current is known as the ammeter. The current is the flow of electrons whose unit is ampere. Hence the instrument which measures the flows of current in ampere is known as ampere meter or ammeter.

The ideal ammeter has zero internal resistance. But practically the ammeter has small internal resistance. The measuring range of the ammeter depends on the value of resistance.

The capital alphabet A represents the ammeter in the circuit.

By the current, the ammeter categorises into two types.

AC ammeter
DC ammeter
