Significance of ammeter
WebAn ammeter is a device that measures current, either alternating or direct. Ampere is considered as the unit of current, as we all know. This instrument is known as an ammeter because it measures the value in amperes. The ammeter is usually linked in series with the circuit to measure the current. WebAn ammeter (abbreviation of Ampere meter) is an instrument used to measure the current in a circuit. Electric currents are measured in …
