Answer 1

Answer:

A carbon resistor of (54 ± 2.7) MW is to be marked with rings of different colours for its identification. The colour code sequence will be

Green – Yellow – Blue – Gold

Explanation:

Colour code of carbon resistor

Sol. : 54 MΩ = 54 × 106 Ω

Colour band : Green (5), Yellow (4), Blue (6)

Tolerance limit  =2.7/54x100=5%

Colour band for tolerance limit : Gold

So, sequence : Green – Yellow – Blue – Gold
