Resistor

A resistor can come in a great variety of different packages. And regardless of the form it comes in, the job of a resistor is to resist or limit current.

If you have ever seen a little tube with wires on both sides and little color rings around the tube, you have visually identified a resistor.

The colors are values telling you the amount of resistance in ohms (W).

Figure 11: Carbon resistors. The bands of paint are value displays.

 

[spacer]How to Read Color Codes on Resistors

Locate the Gold or Silver Band. Go to the other end to start counting. Look up the numbers for 1st two colors. Use band 3 as a multiplier.

Gold band = 5% of rating, Silver 10% of rating.
