Question

What are cells mention the types of cells in physics'

Answer 1

Answer:

cells are batteries.

Electrochemical batteries are classified into 3 broad categories.

1. A primary cell
2. A secondary cell
3. reserve or fuel cell system.

Answer 2

A cell is a single electrical energy source which uses chemical reactions to produce current.

It converts stored chemical energy into electrical potential energy which produces current.

Types of Cells:

There are 2 types of cells namely Primary cell and Secondary cell.

Primary Cell:

• These are the cells where the redox reactions proceed in only one direction.
• The reactants in these cells are consumed after a certain period of time, rendering them dead.
• A primary cell cannot be used once the chemicals inside it are exhausted.
• Example: Dry cell - It is the household battery that is commonly used to power TV remotes, clocks, and other devices.

Secondary Cell:

• These types of cells can be recharged after use by passing current through the electrodes in the opposite direction, i.e. from the negative terminal to the positive terminal.
• Example: Lead storage battery that is used in automobiles and inverters can be recharged after some time.
