A 2.2 k resistor would be banded red, red, red, and possibly other bands depending on tolerance, etc.
The first two bands, red and red, mean 2 and 2. The third band means 2 zeros. The result is 2200.
0 black
1 brown
2 red
3 orange
4 yellow
5 green
6 blue
7 violet
8 grey
9 white
Fourth band:
none 20%
silver 10%
gold 5%
If the third band is gold or silver, then the multiplier is 0.1 or 0.01, respectively. For example, red, red, silver means 0.22 ohms.
Red (2) Red (2) and Red (2 zeroes). There may be a fourth and fifth band for tolerance and temperature cooeficient.
Red (2), Red(2), Red (X100)
Red,Red,Red
if a diode has color band markings they are on the cathode end
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%.
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.
It's the tolerance of the resistor - +/- 10% (grey), 5% (tan/orange), 2% (red), 1% (dark red/maroon), etc.
yep
Its red red red
2 red 2 red 2 zeros=red red,red,red that's assuming you meant 2.2K
A megohm is 1,000,000 ohms, so 2.2 megohms is 2,200,000 ohms, often abbreviated to 2.2M, or 2.2Mohm, or 2M2.

white case with a brown band and black markings
On a standard four band resistor: yellow, violet, black, and gold.
Green - Black - Red, but this is not a standard value. You probably want a 5.1K resistor, and that is Green, Brown, Red
white case with a brown band and black markings
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%.

Black is never the first band of a resistor color code, so you must be reading the stripes backwards. Orange-Orange-Black = 33 ohms.
