Ampere (A) is the SI unit of electric current. It is named after the French physicist André-Marie Ampère.
SI Unit: Ampere (A).
Formula: I = Q/t (1 A = 1 C/s).
1 Coulomb = charge of 6.242 × 10¹⁸ electrons.
Named After: André-Marie Ampère.
Definition 1 (Simple): 1 Ampere is the amount of electric current that flows through a conductor when 1 Coulomb of charge passes through a cross-section of the conductor in 1 second.
Formula: I = Q/t Where: I = Current (Ampere), Q = Charge (Coulomb), t = Time (seconds)
So: 1 A = 1 C / 1 s
Since 2019, the Ampere is officially defined as: 'The electric current corresponding to the flow of exactly 6.242 × 10¹⁸ elementary charges (electrons) per second.'
1 Ampere is the electric current when 1 Coulomb of charge flows through a conductor in 1 second.
The SI unit of electric current is the Ampere (A).
