Answer 1

Answer: (A)

$1.$ Bulb work by heating up a small wire called a filament. Electric current heats the filament so much that it glows.

$2.$ This bulb really is more of a heating element that happens to put out some light.

$3.$ In fact, $90\%$ of the electricity used by a bulb is converted to heat and this conversion is wastage.

$4.$ Whereas, the CFL is just like standard fluorescent light, compact and work by exciting gases with electricity.

$5.$ Because little heat is generated, most of the electricity used goes directly into providing light.

So, since bulb produce more heat and results in wastage of electricity and CFL saves electricity, that"s why CFL is better in comparison to bulb.
