In wirewound resistors, another selection factor is the temperature characteristic of the wire. The resistance of all materials changes as their temperature changes. If the temperature is lowered, resistance (typically) declines. In fact, if cooled sufficiently, the...

All materials are either conductors or insulators; a material will either conduct electrical current, or impede its flow. Not all conductors are equally capable of supporting current flow. Copper is a better conductor than nickel. Silver is a better conductor than...

There are several ways to make resistors for electrical or electronic circuits. Carbon resistors are made by attaching leads to a bar or rod of carbon material. The material is usually made by suspending carbon particles in a plastic material. The material “mix...
