Ampeerimittari
Ampeerimittari, often called an ammeter, is an electrical instrument used to measure electric current. Electric current is the flow of electric charge, and its standard unit of measurement is the ampere (A). An ammeter is designed to be inserted into a circuit in series, meaning that the current to be measured must flow through the ammeter itself. This allows the instrument to directly quantify the rate of charge flow.
Historically, ammeters were mechanical devices employing a galvanometer, which utilizes the magnetic field produced by a
When using an ammeter, it is crucial to connect it correctly. Connecting an ammeter in parallel, across
