What does the first band on a resistor mean?

What does the first band on a resistor mean?

Cracking the Resistor Color Code. The first few bands always represent digits in the value of resistance. Then you will find a multiplier band to signify moving the decimal right or left. The last bands represent tolerance and the temperature coefficient.

What is band in resistor?

The color code is given by several bands. Together they specify the resistance value, the tolerance, and sometimes the reliability or failure rate. The number of bands varies from three to six. At a minimum, two bands indicate the resistance value and one band serves as multiplier.

What is the color code for 1 ohm resistor?

The color code in tabular form for the 1R four-band resistor is brown, black, gold, gold.

What is the third band on a resistor used for?

The third band is called a Multiplier, this means the number of zeros you add after the first two digits to get the Ohm value (example: brown = 0). So one zero is added after the first two numbers. Therefore 220 ohms is the resistance value of the resistor.

Are resistance bands color coded?

Resistance bands are often color-coded to denote varying resistance levels. The resistance level is the amount of tension the band offers to you during an exercise. The four main categories of resistance found in resistance bands are: light, medium, heavy, and extra-heavy.

What is band 1 and 2 in a resistor?

For a four band resistor, each band has a specific role: Band One – 1st Digit: This is the first digit of the resistance value. The first band is brown, which corresponds to the value 1. Band Two – 2nd Digit: The second digit of the resistance value.

What is the color code on a 4 band resistor?

Resistor color codes always have digits, followed by a multiplier, follower by a tolerance value. For a four band resistor, each band has a specific role: Band One – 1st Digit: This is the first digit of the resistance value. The first band is brown, which corresponds to the value 1.

What is the value of 100 ohm resistor with 4 bands?

The color code for the four bands 100 Ohm resistor is brown, black, brown, gold. Theoretically, the value of 100 Ω resistor is between 95 Ω to 105 Ω. In 4- and 5-band resistors, the last band indicates the resistor’s tolerance value. It is Gold in this case, indicating a tolerance value of 5%.

How can we read the resistance value according to the resistors’color?

We can read the resistance value according to the resistors’ color code because of the use of four-color bands or five color bands or six color bands on the resistors to indicate the resistance value. The color information representing the resistance value can be read at once from any angle.
