Ampere is a measure of electrical current or the rate at which electrons flow. One ampere of current flows when one volt is applied across one ohm of resistance. One coulomb of electrical charge, or 6.24 1018 charge carriers, moves in a second in one ampere of current.
What is the Origin of Amp?
The word “ampere” is derived from the French word “ampère,” which is used to describe the amount of electricity that a volt can transmit through one ohm of resistance. The term is taken from André-Marie Ampère, a French physicist who made this idea known in 1881. The term “amp” was first used to shorten the original word in 1886.

Where is an Ampere Used?
The physics concept of this word is used to gauge the intensity of an electrical current. Today, both scientists and technology professionals use this measurement, which was initially discovered in the late 19th century by a French physicist.
An electrical instrument called an ampere meter, also called an ammeter, is used to measure electrical current in amperes. By attaching this meter in series to the load, it is possible to measure the electrical current flowing through the load. Given that it has no resistance, the measured circuit is unaffected.
