A carbon resistance of 4.7 kΩ is to be marked with strips or bands of different colours for its identification. The sequence of colours would be:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → yellow, violet, red
Given,
Resistance = $4.7 kΩ=4.7×10^3Ω$
Here's the breakdown:
- First digit (4): The first digit is 4, which corresponds to Yellow.
- Second digit (7): The second digit is 7, which corresponds to Violet.
- Multiplier (× 1,000): The multiplier is 1,000 (since it's 4.7 kΩ), which corresponds to Red.
