Question

What is an ammeter?

Answer 1

1. Ammeter: The ammeter is a current measuring instrument. In an electrical circuit, the ammeter's two leads must be linked in series. The current is measured by the ammeter when the current runs through it.
2. The formula for the ammeter: The relationship between the current and the resistance in an electric circuit is given by Ohm’s law as: $I=V/R$ Where $I$ is the current through the circuit ,$V$ is the voltage and $R$ is the resistance of the circuit.
