How can a technician identify a wire wound resistor that is color coded?

The same way he/she can identify a composite resistor that is color coded or a metal film resistor that is color coded: by reading the color code bands. They all use the same color code. If for some reason the color bands are damaged and unreadable, the resistor will have to be removed and measured with a meter. However this reading may be incorrect as whatever caused the color bands to become unreadable may have also damaged the resistor, changing its value. Verify the value on the schematic!


What is the color code of resistor value 0.1?

A 0.1 ohm resistor is color coded brown (1) black(0) silver (x 10-2).


Why is pex tubing color coded?

Pex tubing was manufactured for plumbing. The actual tubing comes in two colors, red, and blue. These are to signal hot and cold when you are running the tubing.


What is the color code for condensate pipe?

The color code for condensate pipes typically follows the standards set by organizations like ASHRAE or local building codes. Generally, condensate pipes are often color-coded blue to indicate their function as drainage for condensate from HVAC systems. However, it's essential to check local regulations, as color codes can vary by region. Always refer to specific local codes for the most accurate information.


How to identify a 470 ohm resistor?

Resistors are color coded to denote the value of the resistor as well as the multiplier. In your case a 470 ohm would be colored as Yellow Violet Brown corresponding to 4, 7 and a multiplier of 10^1.
