Ammeter and Voltmeter Difference



  • The ammeter is a measurement of current circuit by how many voltage current will produce in the circuit.
  • The ammeter is measure the small amount of current like second and minute of charged particles.
  • The series connection is being attached to the ammeter and measure by the circuit where the current passes through it.
  •  Compared to the voltmeter ammeter having low resistance and perform under the conditions of low voltage.
  •  The consisting ammeter resistance is always equal to the zero particles.
  • The ammeter is the main instrument used to find the value of current and measurement of current.this is called Ammeter.


  • The voltage measuring device is called voltmeter.
  • The voltmeter is connected on a parallel circuit.
  • The polarized of connection voltmeter is like a ammeter.
  • The positive terminal is connected to the positive polarity and negative potential is connected to the negative polarity.
  • The larger voltmeter is connected across the ammeter.
  • This resistance does not allow the current flows through the voltmeter and the point is measured.
  • The approximate value of equal to infity.

Difference between ammeter and voltmeter:

1.The values of small current is measured by the ammeter through the flow in circuit.

2.The potential difference between any two points are attached to the electrical circuit.

3.The current circuit doesn’t disturb the voltage measurement.

4.The complete current circuit connected in the ammeter.

5.The potential difference of the parallel circuit remains in the constant region.

6.The ammeter is compared to the voltmeter.

7.The voltmeter can be increase or decrease by the range of resistance and can’t be changed.
