100 Ohm Resistor-Pack of 10:

A 100-ohm resistor is a type of fixed resistor with a resistance value of 100 ohms. Like other resistors, its purpose is to limit or control the flow of electric current in a circuit. Here are some key points about a 100-ohm resistor:

1. Color Code:
   • The color code for a 100-ohm resistor typically consists of four bands. The color bands represent the digits and multiplier for the resistor value.
   • For a 100-ohm resistor, the color code might be brown, black, brown, and gold. Each color represents a specific digit or multiplier.
2. Numerical Marking:
   • On some resistors, especially smaller ones, the resistance value may be directly printed as numbers. In this case, a 100-ohm resistor might be marked as "100," where the last digit(s) represent the number of zeros to add.
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 100-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 100-ohm resistor with a color code of brown, black, brown, and gold would be read as follows:

• Brown: 1
• Black: 0
• Brown: Multiply by 10
• Gold: Tolerance of ±5%

So, the resistance value would be 10 * 10 with a tolerance of ±5%, resulting in 100 ohms with a possible range of 95 to 105 ohms.
