It measures current by creating a coil around the current carrying wire. Current flowing in the wire induces a current in the amp-meter proportional to the current flowing in the wire.

What do you use to measure an electric current?

An ammeter, either shunt or inductive. A shunt is an inline resistor of a small, known resistance. Knowing the resistance and the voltage one can calculate the amperage by Ohms law, I=V/R. An inductive, or clamp on ammeter measures the magnetic field and using more complex calculations displays the current, typically on a digital display.


Can you use ac ammeter to measure dc current?

It depends. If it's an inductive ammeter (the kind that clamps around a wire), it won't work at all. If it is the type of ammeter that is actually placed in the circuit, it will work but it won't be accurate.CommentActually, modern 'clamp on' ammeters WILL measure d.c. currents. It uses the Hall Effect to measure the current.
