Electric cell

Introduction

Advantages of Electricity

• Light in our houses, offices, roads etc. even past sunset
• To operate pumps which in turn have a lot of applications
• Electrical appliances like refrigerator, fans etc.
• Building houses, installing equipment etc.

Current

• Current is the flow of particles in a particular direction. E.g air currents that cause winds or water currents.
• When particles flow in an electric circuit to produce electricity, it is called an electric current.

Electric current

• The flow of electric charges in a circuit is called an electric current. The direction is taken from the positive terminal to the negative terminal of the battery in an external circuit

Electric cell

Features of an Electric Cell:

• It is a small cylindrical structure which helps in operating the devices.
• A small metal cap is placed on one side and a metal disc is present on the other side.
• All cells have two terminals: Positive and Negative.
• The metal cap and metal disc are positive (+) and negative (-) terminals of the electric cell respectively.
• Chemical energy is converted into electrical energy inside a cell. When the chemicals are exhausted, the cell stops working.

We use electric cells to supply the energy needed for electrons to move around an electric circuit. A battery is a group of two or more electric cells that are connected. The electric cell system works to generate electricity.

Power station: Electricity that we use at homes, in our factories, is supplied from a power station.
