Characteristics of Ohmic and Non-Ohmic Conductors. INTRODUCTION Conduction Conduction takes place in solid matter of certain materials where energy can be transferred from atom to atom. A conductor is a material that allows an energy transfer of this nature to take place. All metals are good conductors of electricity, which is why all circuits contain mostly metal wires and components. When energy is supplied to one part of a conducting wire, the electrons in the wire move from one atom to the next, producing an electrical charge. Semi-conductors are elements such as Silicon and Germanium, which do not conduct at low temperatures, and whose conductivity increases with the temperature. Current, Voltage & Resistance Current electricity is the flow of charged particles through a circuit. In all dry conductors, the charged particles are electrons, therefore the charge is negative. The electrons in a circuit always flow from the negative terminal of a cell...
