The colour code for a resistance of 22 Ω ± 5 % is _____

Options

  1. ABrown - brown - black - gold
  2. Bred - red - brown - silver
  3. Cred - red - black - gold
  4. Dred - red - orange - silver

Correct answer

C. red - red - black - gold

Step-by-step solution

Resistor Colour Coding uses coloured bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating. Resistance = 22   Ω ± 5 % From colour code 22 × 10 0 ± 5 % → red, red - black, gold
