Question

4. A carbon resistance has value R = 2.4 + 5%, then
sequence of colour code is
(1) Red, Yellow, Silver, Golden
(2) Red, Orange, Silver, Golden
(3) Red, Yellow, Golden, Golden
(4) Red, Orange, Golden, Silver​

Answer 1

Hey,

◆ Answer -

(1) Red, Yellow, Silver, Golden

◆ Explaination -

On standard resistor, there are 4 bands.

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

◆ For 2.4 ohm + 5%, resistor -

1st band, Red = 2

2nd band, Yellow = 4

3rd band, Silver = 0 zeroes

4th band, Golden = 5%

Hence, 2.4 ohm + 5%, resistance is represented by Red, Yellow, Silver, Golden code.

Hope that helps you.
