What Is an Ammeter?
An ammeter is an instrument used to measure electric current in a circuit. It helps measure the amount of current flowing through the circuit so that it can be adjusted and regulated accordingly. The ammeter works by measuring the voltage drop across a resistor, usually in series with the load, which then produces a proportional amount of …
