Current
Current, Measured in amperes refers to the rate of the flow of electrons flowing throughout the circuit. Higher Ampere higher rate of electron flow. Current / Amperes can be the measuring unit of charge.
According to Ohm’s Law
Where: I = Current V = Voltage P = Power R = Resistance Rearragements > (

What is Current
Current is the flow of electrons, amperes are the amount of electron flow (1A =
