Solve the following problem.
Find the value of resistance for the following colour code.
Orange White Red Gold
उत्तर
Given: Orange - White - Red - Gold
To find: Value of resistance
Formula: Value of resistance
= (xy × 10z ± T%) Ω
Calculation:
| Colour | Orange (x) |
White (y) |
Red (z) |
Gold T% |
| Code | 3 | 9 | 2 | ±5 |
From formula,
Value of resistance = (39 × 102 ± 5%) Ω
Value of resistance = 3.9 kΩ ± 5%
