An electric current is the flow of electric charge.

Current flows from positive to negative in a circuit.

The formula for finding out current is:


Current in amperes (A) = Charge in coulombs (C) / Time in seconds (s)

Potential Difference is the work done (energy transferred) per coulomb of charge that passes between two points in a circuit, measured in volts.
