1 ampere (A) is the unit of electric current. It is defined as the flow of electric charge through a conductor. Specifically, 1 ampere is the current that flows when 1 coulomb of charge passes through a point in a circuit per second.
In simpler terms, if 1 coulomb (which is a unit of electric charge) moves through a wire every second, the current is 1 ampere.
Mathematically:
\[ 1 \, \text{A} = 1 \, \text{C/s} \]
Where:
- C is coulombs (the unit of electric charge),
- s is seconds (the time period).
So, 1 ampere equals the flow of 1 coulomb of charge per second.
