### How do you identify a fixed resistor?
**1. What is a fixed resistor?**.
A fixed resistor is a type of electronic component that has a fixed resistance value, meaning it cannot be adjusted or changed. It is usually denoted by a color code or numerical value that indicates its resistance.
**2. How do you identify a fixed resistor by its color code?**.
Fixed resistors are often marked with colored bands that represent specific numbers. The color code consists of three to six bands, each representing a digit or a multiplier. By decoding the color bands and following the color code chart, you can determine the resistance value of the fixed resistor.
For example, a resistor with the bands red, red, red, gold would have a resistance value of 2,200 ohms (or 2.2 kilohms) with a tolerance of ±5%.
**3. How do you identify a fixed resistor by its numerical value?**.
Some fixed resistors are labeled with their resistance value directly in numeric form, such as "220 ohms" or "47 kilohms." These resistors do not require decoding of color bands and are straightforward to identify based on the numbers provided.
It is essential to use a multimeter to confirm the resistance value of a fixed resistor accurately. By measuring the resistance across the terminals of the resistor, you can verify if it matches the marked value or the decoded color code.
In conclusion, fixed resistors can be identified by either their color code or numerical value, with the color code providing a visual representation of the resistance value through colored bands. Using a multimeter to test and confirm the resistance value is essential for ensuring the proper functioning of electronic circuits.
