The first three bands on a resistor tell you what its resistance is. The first band is the first digit, the second band is the second digit, and the third band is the number of zeros to add. Use the resistor color code to convert...
0 Black
1 Brown
2 Red
3 Orange
4 Yellow
5 Green
6 Blue
7 Violet
8 Grey
9 White
As an example, a 27000 ohm resistor would be Red - Violet - Orange.
If the third band is Silver, the multiplier is 0.1 and, if the third band is Gold, the multiplier is 0.01. For example, a 0.39 ohm resistor would be Orange - Gray - Gold.

Show you colors for 2.2 kiloohms resistor?
Three red color bands indicate a resistor value of 2,200 ohms (2.2 kohms)
What does the fourth band on a resistor indicate?
It indicates how close the real resistance of the real resistor is guaranteed to be to the numbers indicated by the first three bands. Gold . . . within 5 percent higher or lower Silver . . . within 10 percent higher or lower No 4th band . . . within 20 percent higher or lower
What is the equivalent resistance of three resistor with 3 ohms connected in star?
There is no 'equivalent resistance' for three resistors connected in star.
What is the function of rheostat in this experiment?
A rheostat is the name given to a variable resistor when it is used to control current. When a variable resistor is used to control voltage, we call it a potentiometer.A rheostat is connected in series with a load, and two of its three terminals are used. A potentiometer is connected in parallel with the supply, and each of its three terminals are used.So the terms 'rheostat' and 'potentiometer' are the names given to describe the function of a variable resistor, not the variable resistor itself.
What is the name of a variable resistor with 3 terminals?
It's called a 'variable resistor'. However, it can function as a 'rheostat' (to control current) when two terminals are connected, or as a 'potentiometer' (to control voltage) when three terminals are connected. The terms, 'rheostat' and 'potentiometer' do not describe the device itself, but how it is being used.

A circuit schematic calls for a resistor of 270 ohms what color bands from left to right should you look for to use in the circuit?
Red, Violet, Brown for the first three. The fourth band just indicates the accuracy of this number for that resistor, so you can use any, but use gold for the lowest variation.
How do you work out resisters percentage?
On a color coded resistor, there are normally four color bands. The first three represent the value of the resistor and the fourth represents the tolerance of the resistor, i.e. the acceptable variation as a percentage from the stated value. No fourth band allows +/- 20% Silver allows +/- 10% Gold allows +/- 5% Red allows +/- 2% Brown allows +/- 1%
What does the fourth band on a resistor?
It indicates how close the real resistance of the real resistor is guaranteed to be to the numbers indicated by the first three bands. Gold . . . within 5 percent higher or lower Silver . . . within 10 percent higher or lower No 4th band . . . within 20 percent higher or lower

What are the three methods to determine the value of a resistor?
Basically you can either read the resistance that is printed on the resistor (with a special color code, which you would have to learn), or you can use Ohm's Law, by measuring a voltage through the resistor and the corresponding current. I am not aware of any third method.
How do you identify carbon resistor using colour code?
To identify the value of a carbon resistor using colour code use the following table...0 - Black1 - Brown2 - Red3 - Orange4 - Yellow5 - Green6 - Blue7 - Violet8 - Grey9 - White... and look at the bands. The first two bands will be the digits, and the third band will be the multiplier. For instance, Brown - Red - Orange will be 12000 ohms, where the 1 is the first band, the 2 is the second band, and the three 0's is the third band.If the third band is Gold or Silver, then the multiplier is 0.1 or 0.01 respectively. For instance, Brown - Red - Gold would be 1.2 ohms, and Brown - Red- Silver would be 0.12 ohms.If there is no fourth band, the resistor is +/- 20%. If the fourth band is Silver, the resistor is +/- 10% and, for Gold, +/- 5%.Some high end resistors have more bands. The 1% resistor will have a third digit band, and some resistors will have a band indicating temperature coefficient.
What do the colors on a resistor mean?
Most resistors have either 3 or 4 color bands. The fourth, if it is there, only indicates the tolerance, or how accurate the value is. For the first three bands, the following colors may be used: black = 0 or X1 brown = 1 or X10 red = 2 or X100 orange = 3 or X1000 yellow = 4 or X10000 green = 5 or X100000 blue = 6 or X1000000 violet = 7 gray = 8 white = 9 A resistor uses the first two color bands to form a 2 digit number, then a third band to add a multiplier. For instance, suppose you have a resistor that has a red, violet, brown color code. Decoding: red = 2 violet = 7 27 brown = X10 27 * 10 = 270 In this case, you are holding a 270 ohm resistor. How about a 2.2K resistor? Well, K = 1000, so 2.2K is the same as 2200 ohms. Reverse decoding: The first two bands would have to be red, red (22). To get to 2200 from 22 we have to multiply by 100, so the third band would also be red (X100). The last, or fourth band indicates how close to the nominal value the resistor is. The band colors are: none = 20% silver = 10% gold = 5% So, if the 2.2K resistor is red, red, red, silver, it means the actual resistance can be as much as 10% (or 220 ohms) higher or lower than 2.2K, or anywhere from 1980 ohms to 2420 ohms. You can get resistors with better accuracy than 5%, such as 2%, 1%, 0.1%. Some use three number bands and a fourth multiplier band, others have no bands at all, just the actual resistance printed as a number on the body. If in doubt, measure the resistor with an ohmmeter to be sure.

How do you change a blower motor resistor for a 2000 Chevy S10?
First locate the resistor, it is under the hood, on the firewall, passenger side, close to the blower motor. Unplug the wire connection and remove the three small screws holding it in place, then remove the resistor.
