Ammeter is an instrument that measures electric current in a circuit. (Circuit-Path for transmitting electricity) Amperage is essentially electrical current which is measured in amps. Amps tell you the amount of electrical current flowing through a system, if it is working properly, and how much a system can safely handle. (It can measure current in both homes and businesses) Ammeters can measure both Direct Current and Alternating Current electricity. This one was designed with Direct Current in mind. |
