Question ⤵️
Why Ammeter is used?
Answer ⤵️
Ammeter, instrument for measuring either direct or alternating electric current, in amperes. An ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the meter mechanism; a shunt in parallel with the meter carries the major portion.
Extra Information ⤵️
- How it works?
➡️ Ammeters work to measure electrical current by measuring the current through a set of coils with a very low resistance and inductive reactance. You must connect an ammeter in series when measuring the current of a circuit. The low impedance of the ammeters means it won't lose much power.
- How many types of Ammeter are there?
➡️ By the current, the ammeter categorises into two types. 1. PMMC Ammeter – In PMMC instrument the conductor is placed between the pole of the permanent magnet. When the current flows through the coil, it starts deflecting.
