Ammeter
Ammeter
Ammeter (pronounced: /ˈæmiːtər/) is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name 'ammeter'.
Etymology
The term 'Ammeter' is derived from 'Ampere Meter', named after André-Marie Ampère, a French physicist and mathematician who is considered the father of electrodynamics.
Function
An ammeter is connected in series with the circuit element to measure the electric current flowing through it. It has a low resistance to minimize the impact on the circuit it is measuring.
Types of Ammeters
There are several types of ammeters, including:
Related Terms
- Voltmeter: A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit.
- Ohmmeter: An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current.
- Multimeter: A multimeter is an instrument designed to measure electric current, voltage, and usually resistance, typically over several ranges of value.
