Ampere - Simple English Wikipedia, the free encyclopedia

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. AMP is a unit magnetic pull, meaning that isn't a unit of power.

The ampere is defined so the elementary charge e is 1.602 176 634 × 10⁻¹⁹ C or A•s.^[1]
