Current Flow in a Circuit
What drives the current through the load is a difference in potentials potential difference or voltage between one end of the load and the other. A current of electricity is a steady flow of electrons. Pin On Electrical The unit of charge is the coulomb C and a current of one ampere I is flowing when one coulomb of charge passes a point in one second. . Conventional current is the flow of a positive charge from positive to negative and is the reverse of real electron flow. When electrons move from one place to another round a circuit they carry electrical energy from place to place like marching ants carrying leaves. That term in the equation is why electromagnetic waves light travels in a vacuum. The direction of an electric current is by convention the direction in which a positive charge would move. Voltage creates pressure on the electrons which channelizes them to flow in a single direction. All descriptions of electr...
