What is the color code for a 220 omega.gif 5% resistor?
Red, Red, Brown, Gold
Orange, Orange, Black, Gold
Red, Red, Black, Gold
Red, Red, Brown, Silver
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).

R = AB*10^C +or- D.

Where ABCD are color bands on resistor.

D is the tolerance.
