1000 ohms = 1Kohm; silver is the tolerance band of the resistor. Silver signifies plus or minus 10%. The fourth band is always the tolerance band. If there is no tolerance band, the tolerance is plus or minus 20%. A gold band would signify plus or minus 5%.

What does a resistor measures?
Resistors are measured in units of Ohms (Ω).
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
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
Show you colors for 2.2 kiloohms resistor?
Three red color bands indicate a resistor value of 2,200 ohms (2.2 kohms)
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 is the value of a resistor marked with Brown Yellow White Black bands?
149 ohms, I believe.
Why are there couler bands on a resistor?
i presume you meant colour, but there are colours on resistors so we know what the resistance is.
How is resistance calculated?
You can measure it, but you can't calculate it. That's why the resistance of a resistor is always printed on it, either in numbers or in color bands. Without that marking, the resistor is pretty useless. If it accidentally missed being marked during manufacture, it would be either discarded, or sold surplus for bubkes.
What is the maximum allowable resistance of a 680ohms resistor?
This depends on the tolerance rating of the resistor. There's 1, 2, 5, 10% tolerances. For tighter tolerances, you pay a premium - you can get tolerances as close as .1%. This is defined by one of the bands on the resistor. For a 10% tolerance, the maximum resistance of a 680 ohm resistor could be 748 ohms.
What will be the resistance of carbon resistor having the green and golden colour bands?
Green is 5ohms and gold is 5% tolerance. It depends if there are other bands though. See related link
What will be the resistance of carbon resistor having the green black colour bands?
This question cannot be answered because you did not specify the color of the third band.
What 4 colour bands represent a resistor with resistance of 270 k ohms and a tolerance of 5 percent?
red-violet-yellow-gold
What does a resistor measures?
Resistors are measured in units of Ohms (Ω).
What are resistance bands used for?
Resistance bands are used to strain people's muscles, thus strengthening their bodies. Using resistance bands correctly one can replace a whole gym with resistance bands.
How do manufacturers of resistors indicate the value of the resistance?
They use a color code. Colored bands on the resistor that tell the value. Some precision resistors have their value written on them.
Step in measuring resistance of a resitor?
count up the value of the resistor using the colour bands along with resistor code chart(or it may on the resistor eg. 10kohms, follow this by hooking up an ohm meter(you will have to select ohms, kilo-ohms, mega-ohms whichever applies) , your resistance should appear within the acceptable variable guidelines.. usually 5 to 10 percent(last band or on the resistor itself) count up the value of the resistor using the colour bands along with resistor code chart(or it may on the resistor eg. 10kohms, follow this by hooking up an ohm meter(you will have to select ohms, kilo-ohms, mega-ohms whichever applies) , your resistance should appear within the acceptable variable guidelines.. usually 5 to 10 percent(last band or on the resistor itself)
