(a) Explain why should there be two separate circuits one for high power rating appliances and the other for low power rating appliances.
(b) A domestic circuit uses a \( 5 \mathrm{~A} \) fuse. Find how many bulbs of rating \( 100 \mathrm{~W}-220 \mathrm{~V} \) can be safely used in this circuit? Justify your answer.
