The correct answer is ammeter.

Key Points

  •  An ammeter is a device that measures electric current in a circuit.
  •  It is connected in series with the circuit and measures the flow of current through it.
  • An ammeter is designed to have a very low resistance so that it does not affect the current flowing through the circuit.
  •  It is an essential tool for anyone working with electrical circuits, as it helps in monitoring the current and detecting any faults or abnormalities.


Additional Information 

  •  Odometer: It is an instrument that measures the distance traveled by a vehicle.
  •  Speedometer: It is an instrument that measures the speed of a vehicle.
  • Hygrometer: It is an instrument that measures the humidity in the atmosphere.

  

Difference between an Ammeter and a Galvanometer:

  • The ammeter shows only the magnitude of the current.
  • The galvanometer shows both the direction and magnitude of the current.
