Power plants produce energy by the process of nuclear fusion fission

Power plants produce energy by the process of nuclear fission.

Explanation:

Fission : it is a type of nuclear reaction in which larger unstable nucleus splits into smaller stable nuclei with release in large amount of energy.

The energy released is then used to produce steam which further used to run turbines to produce electrical energy.

Generally, uranium isotopes is used in power plants to produce an energy.

explanation:

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
