Diagram of the definition of the ampere


The ampere or amp (Symbol: A) is the standard unit of electric current. An electric current of one amp is one coulomb per second. The amp is named after André-Marie Ampère who studied electromagnetism.


The amp is defined using two parallel wires placed one metre apart in a vacuum. The wires are very long and very thin. One amp is defined as the current producing an attractive force of 2×10–7newtons per metre of length between these wires.[1]
