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.
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 is the resistance value and tolerance with color bands of gray red black and gold?
The resistance value for the resistor with color bands gray-red-black-gold is 82 ohms with a tolerance of +/- 5%.
What do the different colours on a resistor mean?
The color bands on a resistor indicate its resistance value. Each color corresponds to a digit, which is used to calculate the resistance value based on a specific color code chart. The tolerance of the resistor is also indicated by a separate color band.
How is the polarity of a resistor determined?
Resistors do not have a polarity. BY DEFINITION, a resistor is a device that follows Ohms law, and does so regardless of the polarity in which it is inserted into a circuit. Manufacturers of resistors do all they can to make their resistors follow that definition. One way to make a resistor have no polarity is to build it so that it is mechnically symmetrical about its two leads. Doing so will ensure that it will also be electrically symmetrical, and thus non-polarized
What is the purpose of the colors bands on a fixed resistor?

A resistor is said to have a resistance of 82105 ohms and a tolerance of 5 percent. What coloured bands should it have?
A 5 percent tolerance resistor would only have two significant digits in its stated value, so we are talking about 82000 ohms plus or minus 5%. The coloured bands would be grey (8), red (2), orange (times 1000), and gold (5%).
What do the bands on resistors mean?
in simple terms, band represent numbers, ex:- 10K resistor have different colour code and that is difference from 5k resistor. if you type in google 'resistor colour code' that will describe how to calculate a resistor value. thanks
What do the first 3 bands on a resistor indicate?
The first 3 band on a resistor indicate the value of that resistor.
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 first 3 bands of a 2.2K resistor?
all 3 red
What are the color bands for a 470 ohm resistor?
yellow-violet-brown
Football arm bands?
Coloured arm bands denote the captain. Captains wear usually a yellow arm band.
How do you know how strong a resistor is?
The term "how strong" is meaningless.Its resistance value will be shown either as coloured bands according to the resistor colour code, as a printed number code, or as a printed part number.Its power rating will be shown either by its size, or by a printed power rating.The maximum voltage it can withstand must be determined from manufacturer data sheets.
Show you colors for 2.2 kiloohms resistor?
Three red color bands indicate a resistor value of 2,200 ohms (2.2 kohms)
How can a technician identify a wire wound resistor that is color coded?
The same way he/she can identify a composite resistor that is color coded or a metal film resistor that is color coded: by reading the color code bands. They all use the same color code. If for some reason the color bands are damaged and unreadable, the resistor will have to be removed and measured with a meter. However this reading may be incorrect as whatever caused the color bands to become unreadable may have also damaged the resistor, changing its value. Verify the value on the schematic!
How many resistor colors BANDS ARE THere?
3 to 6 depending on precision and temperature characteristics.
