PLS HELP ME Do some research, and look up the difference between the zinc-carbon battery described in the lesson, and the alkaline battery (shown at the left), which is another common dry cell that we use every day. What are the electrodes made of in the alkaline battery? The electrolyte? Does one type have an advantage over the other?

Explanation:

Alkaline are great for long-term use in a device, such as in a digital camera or game console remote. Carbon zinc batteries are ideal in a situation where one needs to power multiple devices for one occasion, such as when buying many toys during the Christmas season to be used for a few days.

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.
