Paragraph on “Power and Electricity Generation” complete paragraph for Class 9, Class 10, Class 11 and Class 12

Power and Electricity Generation

The advancements made by science and technology have not only developed new sources of power but have also increased our dependence upon it. Without power or electricity nothing from our kitchen blender to the heavy industry would work. Electricity can be seen visibly only when the lightning strikes in the skies. Otherwise it is quietly flowing through the wires in our houses in the form of electrons. A large part of the energy produced in the world is obtained from fossil fuels like coal, oil and natural gas. There are power stations in many countries which use coal or oil as a fuel to generate electricity. Electricity is also generated by turning large turbines with water falling with great force from dams.

Today power stations also produce electricity from Nuclear materials. Power generated by these power stations is first fed into a ‘Transformer’ which substantially boosts the voltage, this voltage is transported through cables to various places. Wherever electricity is required, these cables are connected to a local transformer which reduces the voltage in the electricity to levels which are safer and can be used for the various appliances or machines to be run.

Power is also generated from non-conventional sources like the sunlight, windmills etc. Electricity is of two types i.e. ‘Current Electricity’ and ‘Static Electricity’. The electricity which flows through the wires in our houses is current electricity because it is capable of moving. Static electricity on the other hand is different.

Since all things contain an equal number of positive and negative electrons, they cancel out against each other. An increase in any one of the electrons produces static electricity. If we place a sheet of plastic on a piece of paper, it does not stick to it. If we rub across the plastic and again place it over the paper, it sticks to the paper, this effect is produced because static electricity is created.


The main objective of this website is to provide quality study material to all students (from 1st to 12th class of any board) irrespective of their background as our motto is “Education for Everyone”. It is also a very good platform for teachers who want to share their valuable knowledge.
