What is 1 ampere of current?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
One ampere (1 A) of current means that one coulomb of electric charge (approximately 6.24 × 10¹⁸ electrons) flows past a given point in a circuit every second. To put this in perspective, a typical smartphone charger supplies about 1-2 amperes, while a standard household light bulb draws approximately 0.5-1 ampere. The ampere measurement tells us the rate of electron flow, which directly relates to the amount of work the electrical current can perform.
