1 ampere (A) is the unit of electric current. It represents the flow of electric charge through a conductor (like a wire) in one second.
To put it simply, if you imagine a flow of tiny particles called electrons, 1 ampere means that 1 coulomb (a unit of charge) passes through a wire every second.
In other words, when a current of 1 ampere is flowing, it means that a certain amount of electrical charge is moving through the wire at that rate.
### In a practical sense:
- If you have a 1-ampere current flowing in a wire, you are getting a steady flow of electrical energy that can power things like small devices or light bulbs.
