The colour code for a resistance of is _____
- A Brown - brown - black - gold
- B red - red - brown - silver
- C red - red - black - gold
- D red - red - orange - silver
Answer & Solution
Correct Answer
(C) red - red - black - gold
Step-by-step Solution
Detailed explanation
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 22×100±5%→ red,…
