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.
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.
