Importance of color coding in carbon resistor?

Answer 1

color coding of resistor:black,brown,red,orange,yellow,green,blue,voilet,grey,white

these colors are ranked as:0,1,2,3,4,5,6,7,8,9

tolerance:silver,gold,no color

ratings:5%,10%,20%

Answer 2

The coloured bands on a resistor tell you how much resistance is given by the component. The quality or accuracy is given by a silver of gold band at the end. If you fit a resistor of the wrong type into a circuit it may burn out the resistor or it may stop the circuit from working

Answer 3

Resistors (and other components) are color-coded to make it easier to read their value. Printing the value on the side presents difficulty because the component might be rotated with the letters out of sight, and gradual deterioration of the letters might make them unreadable. Color bands are more reliable and can be read from any angle.

Answer 4

Colour Coding is Used To Know The Value Of The Resistor.

B-BLACK - 0

B-BROWN - 1

R-RED - 2

O-ORANGE - 3

Y-YELLOW - 4

G-GREEN - 5

B-BLUE - 6

V-VOILET - 7

G-GREY - 8

W-WHITE - 9

4 Band Example:{total 4 Colours:4 th colour is tolerance...EX: Gold 5%,Silver 10%....ETC}

example: Resistor Colour Code is BROWN BLACK YELLOW SILVER

1 0 10^4 10%

Last But One colour is multiplier (i.e it is Green Means 10^5, white-10^9)

Resistor Value is = 10*10^4 = 100 K.

example 2:

5 Band : YELLOW WHITE WHITE ORANGE GOLD

4 9 9 10^3 5%(tolerance)

Resistor Value is = 499 Kohm.

Answer 5

They're bands of color telling you the electrical value of the component. Works better when there's not enough space to write it out.

Answer 6

A: Look at it then find the left first band that is first value and continue
