i presume you meant colour, but there are colours on resistors so we know what the resistance is.

Describe the purpose of the coloured bands on a resistor?
The purpose of colored bands on a resistor is to tell whoever is installing the resistor the amount of resistance that particuliar resistor has.
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 is an axial lead resistor?
It's a resistor where the leads (wires) are axial (they come in at the center of each end of the resistor).
What is the rule for voltage across each resistor?
Volt across a resistor = resistance x current through the resistor.
The voltage drop across a resistor is 1.0 V for a current of 3.0 A in the resistor what is the current that will produce a voltage drop of 9.0 V across the resistor?
The resistor is 1/3 of an ohm. A 9 volt drop across the resistor would cause a draw of 27 amps through the resistor. The wattage you would need for that resistor is at least a 243 watts.
Describe the purpose of the coloured bands on a resistor?
The purpose of colored bands on a resistor is to tell whoever is installing the resistor the amount of resistance that particuliar resistor has.
What do the first 3 bands on a resistor indicate?
The first 3 band on a resistor indicate the value of that resistor.
What are the color bands for a 470 ohm resistor?
yellow-violet-brown
What are the first 3 bands of a 2.2K resistor?
all 3 red
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.
What is the purpose of the colors bands on a fixed resistor?
hoy unga why hack mediocres you dirty
What is the main couler of there clothes?
there couler is white
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
How do you read the value off a resistor?
Scroll down to related links and look at "Color Code Calculator - Resistor values with 4 and 5 color bands".
What is the value of a resistor marked with Brown Yellow White Black bands?
149 ohms, I believe.
