Question
A carbon resistor of (47 ± 4.7) kΩ is to be marked with rings of different colours for its identification. The colour code sequence will be
Violet – Yellow – Orange – Silver
Yellow – Violet – Orange – Silver
Green – Orange – Violet – Gold
Yellow – Green – Violet – Gold
Solution
B.
Yellow – Violet – Orange – Silver
Colour code for carbon resistor,
| 0 | Black |
| 1 | Brown |
| 2 | Red |
| 3 | Orange |
| 4 | Yellow |
| 5 | Green |
| 6 | Blue |
| 7 | Violet |
| 8 | Grey |
| 9 | White |
Tolerance:
±5% Gold
± 10% Silver
± 20% No colour
(47±4.7) kΩ = 47 x 103 ± 10%
Therefore, Yellow - Violet - Orange -Silver
