Why ammeters have to be arranged in class and voltmeters in parallel circuit ?

Why ammeters have to be arranged in class and voltmeters in parallel circuit ?
by

1 Answer

Answer :

Ammeter must be added to the class because it measures the flow. When added in parallel, the flow will be divided into two parts. As a result, the exact value of the flow cannot be determined. Again the voltmeter has to be connected in parallel because adding voltage will change the voltage difference. But in parallel the voltage difference does not change.
