An ampere is a unit used to measure the flow of electric current [the movement of electric charges through a conductor]. It is named after the French physicist André-Marie Ampère. One ampere is defined as the amount of electric current that passes through a conductor when one coulomb of charge flows past a given point in one second.
For example, if a light bulb draws 2 amperes of current, it means that 2 coulombs of charge are flowing through it each second. Another example is a smartphone charger that provides 1 ampere of current to charge the phone’s battery.
Very Simple Definition:
An ampere is a unit that measures how electric current flows [the movement of electric charges in a wire]. It tells us how much electricity is flowing through a wire at a certain time.
For example, if a light bulb uses 2 amps, it means that a lot of electricity is flowing through the bulb, and it will be bright. Another example is a phone charger that uses 1 amp to charge the phone’s battery.
