Question

on a resistor of colour band are green,violet,red and gold. Give the information about the resistor

Answer 1

I hope you know the trick of learning the color series {(B)(B) (R)(O)(Y) of (G)reat (B)ritain had very (G)ood (W)ife}
Green : 5
Violet: 7
Red: 2
Gold: ±5%
So resistor == 57 x 10² ±5%

Answer 2

Dear Student,

◆ Answer -

Resistance = 5700 ohm ± 5%.

● Explanation -

On standard resistor, there are 4 bands.

First two band indicates digits, 3rd band indicates no of zeroes and 4th bamd indicates tolerance.

# Values of colour codes-

Black = 0

Brown = 1

Red = 2

Orange = 3

Yellow = 4

Green = 5

Blue = 6

Violet = 7

Grey = 8

White = 9

Here,

1st band, Green = 5

2nd band, Violet = 7

3rd band, Red = 2 zeros

4th band, Gold = 5% tolerance

This band have resistance of 5700 ohm ± 5%.

Thanks dear. Hope this helps you..
