First You need to identify four colors after that each color has some certain value
look up the table-
Black- 0
Brown- 1
Red- 2
Orange- 3
Yellow- 4
Green- 5
Blue- 6
Violet- 7
Gray- 8
White- 9
Golden-5%
silver-10%
no color-20%
DETECTING VALUES FROM COLOR CODE
mark the value of first color after THAN mark the value of second color(marking from left to right) and after that third color has value power of 10, and after that mark the tolerance value
for example --
let the color of resistance is
BROWN-BLACK-ORANGE-GOLDEN
VALUE OF BROWN IS - 1
VALUE OF BLACK IS- 0
VALUE OF ORANGE IS- 10 to the power 3 (1000),BCoz orange has value-3
VALUE OF GOLDEN IS - 5% (IT IS TOLERANCE OF RESISTANCE)
SO THE FINAL VALUE BECOME 10000 OHM +- 5%

What is the resistance and tolerance of a four band resistor with the following colors greenblueorangegold?
the 4 colour resistor colour code is thus: black = 0 brown = 1 red = 2 orange = 3 yellow =4 green = 5 blue = 6 violet = 7 grey = 8 white = 9 the first two numbers are found directly on the table. the third number is not the number, but the number of zeros at the end. therefore the value is yellow = 4, green = 5, and brown equals 1 zero, so the total is 450 ohms. the gold band indicates tolerance. gold is by far the most common, and indicates a tolerance of +/- 5%. therefore the actual value of the resistor could be anywhere between 427.5 and 472.5.
Is it possible to increase wattage in a resistor?
No, it is not possible to increase wattage in a resistor.The resistor is designed with a specific wattage (power) rating, which is a function of its temperature coefficient and thermal transfer characteristics. Altering that would be more complex and costly than simply getting a resistor with a larger power rating.As a quick solution, use four identical resistors, two in series, and those two sets in parallel. The equivalent resistance would be the same, but the power rating, assuming you maintain adequate separation, would be four times greater. Parasitic inductance and capacitance would be slightly different but, that should not matter, depending on the application.
When the ammeter reading is zero and there are four resistor connected in seriesusing voltmeter identify which resistor causes the problem?
The ammeter is reading zero because there is no current flowing. This is because one of the resistors is faulty; the faulty resistor has an "open circuit" (open circuit means there is a broken connection). We know that: Ohms law is: V = I x R (voltage = current x resistance) Therefore because there is zero current in each resistor there will be zero voltage across each resistor. However we also know that: Kirchhoff's voltage law is: V1 +V2 +V3 + … = Vs (the sum of the voltage drops accross each component in a circuit MUST equal the supply (or battery) voltage). But if all the resistors are zero volts, then what component equals the supply (or battery) voltage? The battery voltage is developed across the open circuit… therefore the resistor which is faulty will have a voltage across it equal to the battery voltage. That easy to measure with a volt meter! hope this helps
Four equal-value resistors are in a series with a 5v source and a current of 1 mA is measured What is the value of each resistor?
1.25kFollowing Ohms LawEquation:R = E / I(R=Resistance, E=Voltage, I=Current)Known Values:E = 5vI = 1mA = 0.001AR = 5/0.001R=5000Total Resistance is 5000ohms, since we know there are four equal resistors simply divide by 4R/4=5000/4R=1250ohm=1.25kohm
How do you find value of resitor?
In a Resister u can find totally FORE colored rings.The First three rings used to calculate the value of the resister while the fourth ring indicates the tolerance. Let i say an example how to calculate the value of a resister. there are 10 colors commonly using in resister.Each color indicates a value. let me say it. Black-0 Brown-1 Red-2 Orange-3 Yellow-4 Green-5 Blue-6 Violet-7 Grey-8 White-9 A residter has 1.Yellow 2.Violet 3.Brown 4.Gold So yellow value is 4,Violet value is 7,Brown value is 1 So 47(Yellow)(Violet)*10^1(Brown) =470 Ohm and gold indicates +/- 5% tolerance. That is min value of that resistor is 446.5 Ohh and max value of that resistor is493.5 Ohm. Note: Most of the resistor have Four rings only. But aso there are resistors available with 5 rings
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%
A list of one man bands?
two man bands three man bands and four man bands
What is the resistor color code and how is it used to identify and select resistors?
The resistor color code use to help to identify the resistance of the resistor. There are four color in the resistor that help to identify the resistance of the resistor. The first and second color represent the numerical value of the resistor. The third color represent the multiplier. The four color represent the tolerance.
Name bands like the letterman group?
four freshmen four aces
Whats the purpose of the four color theorem?
Four colours are used to colour a map or pattern so that no colour is next to the same colour.
How do you install a blower resistor in Mitsibushi Lancer?
under the glove box look for four wire plug connected. remove screws and resistor is out
What are the color codes on a 47 Ohm resistor with a tolerance of 5 percent?
On a standard four band resistor: yellow, violet, black, and gold.
Current through a resistor doubles power consumption does what?
Four times as much.
What is the current running through resistor four if its 18 ohms?
There is insufficient information in the question to properly answer it. You need to provide more information, such as the voltage across resistor four, or more details about the rest of the ciricuit. Please restate the question.
Name four common parts of an electric circuit?
Transistor, resistor, diode, output.
What are four basic componets for a simple elcetric currict?
power source conductor resistor switch
