Resistor and Capacitor Codes
This project uses different types of resistors and capacitors. The diagrams below will assist
you in locating and identifying values, tolerances and ratings for the various circuit
requirements for your project.
Resistor Power Ratings
Not only are resistors graded by their values but also by their power ratings. Power ratings
are determined by how much heat (power) can be safely dissipated by the resistor. Higher
ratings are usually indicated by larger sizes.
Below are photos and descriptions of various resistors that could be used in this project.
