Voltage and Current Principles

Voltage, electromotive force (emf), or potential difference is described as the pressure or force that causes electrons to move in a conductor. Electron current, or amperage, is described as the movement of free electrons through a conductor. This course introduces the principles of voltage and current through a discussion of the components of an atom and their charges as well as electrostatic forces, electromotive forces, and free electrons.
