- A 47 k � , 10%
- B 4.7 k � , 5%
- C 470 � , 5%
- D 470 k � , 5%
Step-by-Step Verified Solution
As per colour coding Short explanation must be given to understand the trick
Yellow = 4; Violet = 7 ; Brown = 1
Tolerance for Gold is 5%
First colour gives first digit, second colour gives the second digit and third colour gives the multiplier and fourth colour gives tolerance.
_ Resistance R = 47 _ 10 1 � 5 % = 470 � 5 %
