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).

The best way to remember the colour coding is to create it in your own sentence, or format.

Formula: (AB)*10^C.
A=RED.
B=RED.
C=BROWN.
A=RED.
B=RED.
C=BROWN.

We read "B B ROY of Great Britain Visited Gate Way of India".
1st 2 digits are digits 2 & 2.
3rd is multiple. For brown (1) it is 10 to the power 1.
So it is 22x10 = 220.

Absolutely write about color coding. I agree with Neha panday but what about next three color bands.
