I first started understanding that maybe there was something to these resistors when I tried connecting an LED directly to my 9V battery. At first, it seemed to work fine. The LED lit up brightly. But then, after a few seconds, the LED turned really hot. So hot I almost burned my fin...
Resistor values are indicated on the body of resistors using a color code, though on sub-miniature components the value is often printed in alphanumeric characters (and may need a magnifying glass to read). See Appendix B for details of the color code, and websites that show the shape of...
We can't determine a resistor's wattage from its color code (learn how to calculate it with our resistor color code calculator!), but its size can help us here. A resistor's size varies according to its wattage or power rating. For example, the smallest carbon composition resistor's powe...
