Question

Give reason: (a) CFL's are preferred over electric bulbs. __________________________________________________________________________ b) Copper wire used in household circuits does not get hot, but nichrome wire does. __________________________________________________________________________

Answer 1

Answer:

b

Explanation:

nichrome wire has high resistivity

high melting point

it cannot be used for a long time without oxidised

Answer 2

a)CFL's are preferred over electric bulbs.because it consume less voltage and work even in low voltage

b)Copper wire used in household circuits does not get hot, but nichrome wire does because copper wire is produce less resistance then nichrome wire but nichrome wire produce high resistance
