Question

_____is used to measure electric current​

Answer 1

Explanation:

AMMETER - An instrument for measuring the flow of electrical current in amperes

Answer 2

Answer:

Ammeter is used to measure electric current.

Explanation:

An ammeter is an instrument used to measure the magnitude of current flowing in a circuit. It is joined in series in a circuit so that the entire current of the circuit passes through it. It is symbolically represented by the letter A enclosed in a circle. The + sign marked at one terminal of it indicates the current must enter it through this terminal. Therefore this terminal is connected to the higher potential terminal of the current source. An ammeter must have a very low resistance so that the resistance of the circuit may not alter when it is joined in the circuit. It has a calibrated dial on which deflection of needle shows the magnitude of current  flowing in that circuit.
