To measure which of the following is an ammeter used?

To measure which of the following is an ammeter used? Correct Answer Electric current

Explanation:

  • Electric current is defined as the rate of flow of charge or electron, so its direction is the flow of positive charge.
  • SI unit of electricity is Ampere(A) and it is a scalar quantity.
  • Resistance is the opposition delivered by the conductor through which the current flows.
  • A device that is used to measure electric current in a circuit is called ammeter. The resistance of an ideal ammeter is always Zero and is always connected to the circuit in series.
  • A voltmeter is a device which is used to measure the potential difference between the two points in a circuit. The resistance of an ideal voltmeter is infinite.
  • A galvanometer is a device that is used to detect and measure small electric currents in any circuit. It can measure current up to 10-6 Ampere.
  • Now, the interesting fact is:
    • We can convert a Galvanometer into an ammeter by connecting a shunt parallel to it.
    • A shunt is a small wire having very low resistance
    • We can also convert a Galvanometer into a voltmeter by connecting a very high resistance in series.
