But while electrons are the charge carriers in metal wires, the charge carriers in other circuits can be positive charges, negative charges or both. Current electricity is the most common form of electricity that is used to power up devices and appliances. One ampere of current is defined as one coulomb of electrical charge moving past a unique point in a second. From this discussion, we can see two things that current is not : It is not an actual "flow" of electrons in the everyday sense of the word: If we examine the speed given to the electrons by the field, it is usually very small, on the order of millimeters per second. The process is similar to flowing of a river in one direction. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit.
