Expert Answer:

An ammeter consists of a coil with very low resistance. when electric current flows through the coil, the coil induces a magnetic field which turns the needle.An ammeter is a measuring instrument used to measure the electric current in a circuit. Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters.
