Open in App

Solution

Ammeter Voltmeter
An ammeter measures the flow of current. A voltmeter measures emf or voltage at every two points in an electrical circuit.
An Ammeter has low resistance. A voltmeter has a high resistance.
The ammeter is connected in series with the circuit. The voltmeter is connected in a parallel connection with the circuit.
An ideal ammeter has zero resistance. An ideal voltage has infinite resistance.
