Solution

The correct option is B Statement 1 is incorrect and statement 2 is correct.

Electric incandescent bulbs and compact fluorescent bulb (CFLs) both are used for lighting but also give out heat. Heat energy produced by the electric incandescent bulb is more than compact fluorescent lamps (CFLs).
Therefore, incandescent bulbs consume more energy as compared to CFLs.

Statement 1: It is observed that sometimes an incandescent bulb glows brighter and sometimes it glows dim.

Statement 2: Glowing brighter and dimmer depends on heating effect of current. More current produces more heating effect making the bulb glow brighter and vice-versa.

Which of these do you think uses less electrical energy - electric bulb or LED?

Ans) LED will use very little electrical energy .In an electric bulb most of the electrical energy gets converted into heat energy and very little light energy is given out . Whereas in LED more light energy is given out as compared to electric bulb and little heat energy is produced.
