All about resistors, how to identify and use them. Read the full article here: http://www.thedoityourselfworld.com/articles/article.php?id=11516
A resistor is about the most common component in a circuit today. A resistor does just what its name implies - it resists the flow of electricity.
Shown in the video are how to identify a resistor and how to read the color codes.
Also shown are how to read a resistor schematic diagram in a circuit.
The video also covers the variable resistor, or potentiometer. This is an adjustable resistor. This means that you can adjust its ability to resist the flow of electricity in an electronic circuit.
