Question

Find the difference between the ammeter and the voltmeter.

Answer 1

The ammeter and voltmeter, both the devices are connected in a circuit in order to measure the various aspects of the electricity. Ammeters can be used to measure the value of the electric current while the voltmeter can be used for measuring the voltage or the potential difference between two points in the circuit.

Complete answer:

| Ammeter| Voltmeter
---|---|---
Use| It has been used to measure the flow of electric current in a circuit.| It has been used in order to measure the voltage or the potential in a circuit.
Connection| It will always be connected in series with the electrical circuit element.| It will always be connected in parallel with the electrical circuit element.
Resistance| The resistance of the ammeter is low such that it will not affect the flow of current in the circuit.| The resistance of voltmeter is high in order for measuring the potential difference between two points in the circuit.
Range| The range of an ammeter can be varied.| The range of voltmeter can be varied.
Accuracy| It measures the values of electric current accurately.| An ideal voltmeter is supposed to have infinite resistance.
Ideal case| An ideal ammeter is supposed to have a zero resistance. However it will not be practically possible.| An ideal voltmeter is supposed to have infinite resistance.
Representation| $A$ is used to denote ammeter.| $V$ is used to denote a voltmeter.

Note:
There are two ways how we can measure electricity in a circuit. The first one is by measuring electric current where the ammeter has been used and the other one will be by measuring the voltage difference between the voltmeter and the ammeter is that the ammeter comes in handy for measuring the flow of electric current whereas the voltmeter comes in handy for measuring the voltage or the electromotive force across two points in an electric circuit.
