What Happens if Ammeter Connected in Parallel and Voltmeter Connected in Series?

by

It is a well known fact that Ammeter is always connected in series with the element through which current is to be measured. Figure below shows two cases, in one case ammeter connected in series while in other case, ammeter is connected in parallel. As an Ammeter has very low internal resistance therefore ammeter connected … Read more

Why Swamping Resistance in Ammeter?

by

Swamping Resistance in Ammeter can be well understood if we investigate the Effect of Temperature change in the Reading of an Ammeter. Ammeter is basically moving Coil instrument and flow of current through the coil decides the deflection of Ammeter. Now if there is change in the temperature then correspondingly there will also be a … Read more
