NEET 2023 Physics Colour Code of Resistors MCQ Question

Type: MCQ-Medium-Class 12

Resistance of a carbon resistor determined from colour codes is (22000 ± 5%) Ω. The colour of third band must be :

A

Green

B

Orange

C

Yellow

D

Red

Correct Answer

Option B

Detailed Explanation

The value is 22000 Ω=22×103 Ω22000\,\Omega = 22 \times 10^3\,\Omega.

In the resistor colour code:

  • 1st band (Red): significant digit 2
  • 2nd band (Red): significant digit 2
  • 3rd band (Orange): multiplier 103=100010^3 = 1000
  • 4th band (Gold): tolerance ±5%

Therefore, the third band is Orange (multiplier 10310^3).
