Question

The Color Coding is used to indicate value/rating of Resistor

• A. Alphabetical
• B. Resistance
• C. a & c are correct
• D. Numerical

Answer 1

Answer: (B)

Resistance

Answer 2

The color coding on a resistor is a standard system used to indicate its resistance value and tolerance. Each color band corresponds to a specific numerical digit, a multiplier, or a tolerance percentage. By reading these bands in sequence, one can determine the resistor's value in ohms.

Therefore, the primary purpose of the color coding is to indicate the Resistance of the resistor.

• Alphabetical: This is incorrect. Color codes represent numerical values, not alphabetical ones.
• Resistance: This is correct. The entire system of color coding is designed to convey the resistance value and tolerance of the component.
• a & c are correct: This option is incorrect because 'Alphabetical' is incorrect. Also, the option structure is somewhat ambiguous as there is no explicit 'c' option.
• Numerical: While the individual color bands represent numerical values (digits), the overall "Color Coding" system is used to indicate the Resistance value. "Resistance" is a more direct and complete answer to what the coding indicates about the resistor's "value/rating".
