It is a potentiometer.
Instrument used to measure dc current
Ammeter
It measures the current.
A variable that could influence the accuracy of an instrument is the reference standard that was used to calibrate the instrument.
A variable that could influence the accuracy of an instrument is the reference standard that was used to calibrate the instrument.
Either an ammeter or a galvanometer is.
An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
calibration of an ammeter is done in order to standardise the instrument,and rectify the errors present in the instrument, if any.
An ammeter is commonly used to detect electron flow in a circuit. The ammeter measures the amount of current (flow of electrons) passing through a specific point in the circuit.
A voltmeter and an ammeter
An ammeter is the instrument used to measure current in an electric circuit. It is connected in series in the circuit and provides a reading of the amount of electric current flowing through it.
