Ammeter – An overview
A meter is an electronic device used to measure a specific quantity, forming an integral part of measurement systems. Similarly, an ammeter, also known as an ampere-meter, is a device specifically designed to measure the ampere value, which is the unit of electric current. The ammeter determines the strength of the current flowing through an electrical circuit. As a fundamental instrument in electrical engineering, it measures the flow of electricity with the unit "ampere" denoted by the symbol “A.”
How an Ammeter Works?
Ammeters are designed to work in conjunction with sensitive current detectors, such as a moving coil in a galvanometer. While traditionally analog in nature, modern advancements have introduced digital ammeters equipped with digital displays, such as 7-segment screens. However, even these digital devices rely on analog-to-digital converters (ADCs) integrated within microcontrollers for accurate calculations and display functionalities.
An ideal ammeter has zero resistance to avoid disrupting the circuit it is placed in, effectively acting as a short circuit. However, practical ammeters have a small internal shunt resistance. High-quality ammeters, like those produced by Fluke, are known for their precision and reliability, making them indispensable tools for professionals.
