Some materials allow electric current to flow more freely than others these materials are called conductors other materials are resistant to the flow of electric. The interior of a wirewound resistor consists of a ceramic or fiberglass base wound with resistor wire to the desired resistance value the wire. A short circuit is an electrical circuit that allows a current to travel along an unintended path with in an 'ideal' short circuit, this means there is no resistance and thus no voltage drop across the connection in real circuits, the overloaded wires will also overheat causing damage to the wire's insulation, or starting a fire.
