Question 614: Current Electricity

Question

The color code of a resistance is given below :
The values of resistance and tolerance, respectively, are

Accepted Answer

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.
$ 	herefore $ Resistance R = $47 	imes {10^1} \pm 5\%  = 470 \pm 5\% $
