The purpose of an ammeter is to sense and display the magnitude of the current
flowing through it. When connected in series with a branch of an electrical circuit,
the meter displays the magnitude (and direction) of the current in that path ... which
you can't otherwise tell just by looking at the circuit.

An ammeter is a measuring instrument
used to measure the electric current in a
circuit.
An ammeter measures the current through that part of the circuit into which it is inserted.
a dc ammeter is a ammeter which has three pins and it works by two wires.
A microampere is simply one millionth (1x10-6) of an ampere.
The ammeter is used in series, because you want to measure the current through a circuit. The voltmeter is used in parallel, because you want to measure the voltage across a circuit. If you were to place the voltmeter in series, no current would flow because of the relatively high impedance of the voltmeter. If you were to place the ammeter in parallel, you would create a short-circuit, due to the relatively low impedance of the ammeter.
An ammeter measures amperage not voltage.
An ammeter measures current, an important variable in electronics.
