1). | What is the color code for a 220 5% resistor?
| A | Red, Red, Brown, Gold
| | B | Orange, Orange, Black, Gold
| | C | Red, Red, Black, Gold
| | D | Red, Red, Brown, Silver
| |
| View AnswerANS: | A - | Red, Red, Brown, Gold
|
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)
