Aim:- To study about various Electrical Measuring Devices.

Materials Required:- Different Measuring Devices like Ammeter, Voltmeter, Ohmmeter, Energy meter etc.

Theory:-

Ammeter:- Ammeter is used for measuring Electric Current. Current is measured using the unit Ampere. There are AC ammeters and DC ammeters which can be used for measuring Alternating Current and Direct Current.
