Show you colors for 2.2 kiloohms resistor?
Three red color bands indicate a resistor value of 2,200 ohms (2.2 kohms)
What do the colours on resistor mean?
The colored bands on a resistor represent the resistor value and tolerance. The first two bands indicate the significant digits of the resistance value, the third band represents the multiplier, and the fourth band (if present) indicates the tolerance of the resistor. By decoding these colors, you can determine the resistance value of the resistor.
What are the colors of a resistor and why are they there?
There are many colours for resistor rings but the reason that we have them is to help the resistor reduce the electrical current that is passing through.
What do the lines on the resistor mean?
They are color coded lines (or Bands) that are usually broken down into 2 parts. the first part of the bands are to establish the amount of resistance the resistor is constructed, by design, to perform in a circuit. The second part (which is the usally the last line or band) extablishes the amout of tolarance the designed resistor has. tolorance bands are always silver or gold if they are there but there is a provision where you may not see a tolorance band. There are plenty of electronis sites that can break down the color codes for you. but they are based on a X10, X100, X1000... mutipliers depending on which position the band is located in ie. first, second, third and so on... and for how many there are.
What do the first 3 bands on a resistor indicate?
The first 3 band on a resistor indicate the value of that resistor.
Describe the purpose of the coloured bands on a resistor?
The colored bands on a resistor indicate its resistance value and tolerance. By interpreting the color code, you can determine the resistance value of the resistor and the range within which the actual resistance may vary. This helps in identifying, sorting, and using resistors in electronic circuits.
Why are there couler bands on a resistor?
Color bands are used on resistors to indicate their resistance value and tolerance. Each color represents a digit, and by combining multiple colors, you can determine the resistance value. The bands help quickly identify the resistor's value without needing to use a multimeter or other measuring tools.

What are the color bands for a 470 ohm resistor?

How do you add up the restience of the coloured bands of a resistor?
To determine the resistance value of a resistor using its colored bands, first identify the colors of the first two bands, which represent the first and second significant digits. The third band indicates the multiplier (the power of ten by which to multiply the combined digits). For example, if the first two bands are red (2) and green (5), and the third band is brown (10^1), the resistance would be 25 x 10 = 250 ohms. If there is a fourth band, it usually indicates tolerance.
Why are fixed resistors values indicated by colors?
Because the actual resistor is too small to print numbers, so color bands and math are used instead. I just don't know how to calculate the values.
