What Is the Ratio of Amps to an Ampere?


Quick Answer

The ratio of amps to amperes is 1:1 because amps and amperes represent the same unit of electric current; the term "amp" is simply a shortened version of the term "ampere." This unit is named after the French physicist André-Marie Ampère, who is widely considered the father of electrodynamics.

Full Answer

The ampere, or amp, is the SI unit of measurement for electrical current. An ampere is equivalent to one coulomb, which is the SI unit of measurement for electrical charge per second. Amperes are most commonly used to describe the flow of electric charge through a node in an electrical system.

Electric current is related to electric voltage as described by Ohm's Law, which states that voltage is equal to current multiplied by resistance.
