WebAmmeter Working Principle: The working principle of an ammeter depends on the current flowing along with its resistance. Very little impedance is used inside the ammeter as it must drop the least amount of voltage attached to it. The ammeter is connected to the series of circuits as the current in the series circuit is the same. 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.
