AMMETER Meaning and
Definition
-
An ammeter is an electronic device used for measuring electric current in a circuit. It is designed to provide a precise measurement of the amount of electrical flow passing through a conducting pathway. Ammeters are commonly used in various industries and scientific fields to monitor and analyze current levels.
The device typically consists of a metal coil wound around a bobbin with a small gap through which the current passes. When a current flows through the coil, it creates a magnetic field. The strength of this magnetic field is directly proportional to the amount of electric current passing through the circuit. The ammeter's internal mechanism allows it to convert the magnetic field into a proportional mechanical movement, typically displayed on a calibrated scale.
Ammeters are usually connected in series with the circuit being measured. This involves breaking the circuit and inserting the ammeter into the path, allowing the current to flow through it. It is important to note that ammeters have low resistance to avoid affecting the current reading and potentially altering the behavior of the circuit.
The main purpose of an ammeter is to provide an accurate and precise measurement of the electric current in a circuit. By monitoring current levels, users can assess the performance of electrical systems, identify any faults or abnormalities, and make informed decisions regarding the circuit’s operation and maintenance.

Etymology of AMMETER
The word "ammeter" comes from the combination of two words: "ampere" and "meter".
The term "ampere" refers to the unit of electric current, named after the French physicist André-Marie Ampère, who made significant contributions to the field of electromagnetism in the early 19th century. Ampère's work helped establish the concepts and mathematical formulas for understanding and measuring electric currents.
The term "meter" originated from the Greek word "metron", which means "to measure". Meter is a common suffix used to indicate an instrument or device designed for measuring a specific quantity or property.
Therefore, the word "ammeter" combines "ampere" and "meter" to indicate an instrument specifically designed to measure electric current in amperes.
