Answer 1

Cell

A cell is a single unit of device that converts chemical energy into electrical energy.

It is of two types:

1.) Primary Cell

Primary cells are the ones which cannot be recharged neither reused after the expiration of the lifetime.
Primary cells have high density and get discharged slowly.
Since there is no fluid inside these cells they are also known as dry cells.
The internal resistance is high and the chemical reaction is irreversible. Its initial cost is cheap and also primary cells are easy to use.

2.) Secondary Cell

Secondary cells need to be recharged when the charge gets over.
Secondary cells have low energy density and are made of molten salts and wet cells.
The internal resistance is low and the chemical reaction is reversible.
Its initial cost is high and is a little complicated to use when compared to the primary cell.
