What is the color code for a 220 
5% resistor?
5% resistor?Answer: Option
Explanation:
Resistor colour coding series:
Black 0
Brown 1
Red 2
Orange 3
Yellow 4
Green 5
Blue 6
Violet 7
Gray 8
White 9
None 20%
Silver 10%
Gold 5%
Therefore Red, Red, Brown, Gold
2 2 101 5%
= 22 x 10 = 220 ohm 5% (tolerance).

From which side, we should start to see the colors in RESISTORS for saying the color coding properly? can you say any identification to take any color as first color?

Another remembering procedure is:
B B ROY Good Boy Very Good Wife Good Son No problem.
Black 0
Brown 1
Red 2
Orange 3
Yellow 4
Green 5
Blue 6
violet 7
Gray 8
White 9
Gold 5%
Silver 10%
Noring 20%
And for determining the colour coding of a resistor you need to remember the formula :
That is :-
ab*10^c+-tolerance.
Some important points to remember :
> Each resistor has a tolerance ring. Generally they have golden or silver ring for this purpose.
> Sometimes other colours are also used for tolerance.
> The value of a carbon resistor may be obtained by looking at the coloured rings painted on it. Each colour has a numerical value.
> Hold the resistor such that the tolerance ring is on your extreme right. Now take the values of the resistor.
