220 Ohm Resistor-Pack of 10:

A 220k-ohm resistor is a fixed resistor with a resistance value of 220,000 ohms. Resistors are used in electronic circuits to limit or control the flow of electric current. Here are some details about a 220k-ohm resistor:

1. Color Code:
   • The color code for a 220k-ohm resistor typically consists of four bands. The color bands represent the digits and multiplier for the resistor value.
   • For a 220k-ohm resistor, the color code might be red, red, yellow, and gold. Each color represents a specific digit or multiplier.
2. Numerical Marking:
   • On some resistors, the resistance value may be directly printed as numbers. In this case, a 220k-ohm resistor might be marked as "220K," where the 'K' represents the multiplier (kilo).
3. Tolerance:
   • The tolerance band indicates the permissible variation from the specified resistance value. A gold band typically denotes a tolerance of ±5% for a 220k-ohm resistor. This means that the actual resistance of the resistor may fall within 5% above or below the stated value.
4. Power Rating:
   • The power rating of a resistor indicates the amount of power it can safely dissipate without overheating. Common power ratings for resistors are 1/8W, 1/4W, 1/2W, and higher. The power rating is not usually indicated by color coding.

For example, a 220k-ohm resistor with a color code of red, red, yellow, and gold would be read as follows:

• Red: 2
• Red: 2
• Yellow: Multiply by 10,000 (since yellow corresponds to 10^4)
• Gold: Tolerance of ±5%

So, the resistance value would be 22 * 10,000 with a tolerance of ±5%, resulting in 220,000 ohms (or 220k ohms) with a possible range of 209,000 to 231,000 ohms.
