How do Resistors work?
Resistors work by restricting the flow of electrons. The amount of resistance is dictated by the length, cross-sectional area, and type of resistive material.
Different types of Resistors:
Carbon Film/Metal Film Resistors have a ceramic core coated with a carbon composite or metal film etched in a helical pattern. As the helix’s pitch decreases, the path electrons take between terminals increases, which creates more resistance.
Wirewound Resistors contain a thin conductive wire wrapped around a non-conductive ceramic core. More turns and a thinner wire increase the resistance.
SMD Resistors are composed of a carbon composite coat deposited onto a ceramic substrate. The film is etched away until the desired resistance is reached.
