BLACK-0
BROWN-1
RED -2
ORANGE-3
YELLOW-4
GREEN-5
BLUE -6
VIOLET-7
GREY -8
WHITE-9


The first band gives the first digit.
The second band gives the second digit.
The third band indicates the number of zeros.
The fourth band is used to shows the tolerance (precision) of the resistor

4700 means,

4 =yellow
7 =violet
00 =red(10^2)
Ten percent tollerance =silver
So, =4700.

There tolerance is not given so asume it is minimum.

Surajit said:   1 decade ago
Yellow-4
Violet-7
Red-2
Silver-10% tolerance
So the resistor is (47*10^2)
4700 ohm

@dinesh
10% tolerance is given yar....

Thanks @surajat.

Yellow-4
Violet-7
Red-2
Silver - 10% tolerance.

So the resistor is {47*10^2}.

4700 ohm.

What mean by 10% tolerance of silver?

Shrikant said:   1 decade ago
Please anyone explain this question.

@Anita.

Gold and silver are given for extra colour code and for tolerance. It does not have any code. It gives only tolerance. Gold-5% and Silver 10%.
