What is the color code sequence on a carbon resistor having a nominal resistance of 47 kΩ ± 10%?
Answer and explanation
Correct answer: A. Yellow - Violet - Orange - Silver
- First digit (4): Yellow,
- Second digit (7): Violet,
- Multiplier (): Orange.
- Second digit (7): Violet,
- Multiplier (): Orange.
- Step 1: Express the resistance in standard scientific notation: .
- Step 2: Decode each digit according to the color code (BBROYGBVGW):
- Step 3: Tolerance band for is Silver (Gold is , Silver is , No band is ).
- Step 4: The complete sequence is Yellow - Violet - Orange - Silver.
Answer
Yellow - Violet - Orange - Silver
Why not the others: 'Yellow - Violet - Red - Gold' represents ; 'Orange - Blue - Yellow - Silver' represents ; 'Green - Blue - Orange - Gold' represents .
