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:

yellow, violet, red

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.
