Current: Denoted by  I  and measured in Amperes (A).
 

Electric current is a measure of the amount of charge which pass through a point in any given instance of time. Or how much electricity is going through the wires. Current is measured in Amperes (amps).
One amp is technically defined as one coulomb of charge passing a point in one second.

I = q/t  where
 

 I = current   (Amperes )
q = change in charge (Coulomb )
 t = change in time (s)
