Information is constantly flowing through organizations The flow of electricity is commonly called an electric current, or a flow of charge. Switches are used to turn current off (or on) almost instantly, as soon as the charge lacks a place to go (remember, current only moves when there's a full circuit) the current stops. Its like a line of people that only have a dollar, they could all reach out to give a dollar to the person on the right while taking a dollar from the person on the left. density d An electric current is the physical phenomenon of the displacement or flow of an electric charge, usually of electrons, by means of a conductive material. Hole flow is usually called conventional current, and flows from positive to negative. , True or False The frequency of alternating current is the number of complete cycles that occur in a minute. , True or False One cycle occurs when the rotor, or conductor, cuts the magnetic field of a north pole and south pole.
