What are the Uses of Electricity?

The importance of electricity can be seen in our daily lives. We find the application of electricity in various spheres of our life, such as;

  • Working efficiently at our home.

  • Working at our office.

  • We use electricity for accessing data from modes like Fibre, LAN at our workplaces.

  • Electricity consumption in supplying water at our home, etc.


There are ample uses of electricity, uses of electrical energy, and the applications of electricity in different fields, and this page discusses the uses of electricity for Class 6 in detail.


Uses of Electricity

Electricity has changed our lives and has become vital in almost all aspects of our life today. 


The list of uses will fill many books but here are a few applications of electricity in different fields: 

  • Transport Systems - Trains, buses, trams, and cars all use electricity. 

The use of electricity as motive power, meaning that electricity drives the wheels to make the vehicle move. Even gas and diesel-powered vehicles use electricity to start the engines (self in scooters give a spark to the engine), control the engine, and power the ancillary devices. 

  • Home Heating and lighting devices, television, radio, computer, telephones all depend on electricity. 

  • Wireless lights such as solar-powered lamps convert light to electricity. 

  • For communication and providing power for computers, cell phones, fixed phones, etc.

  • We find the application of electrical energy as the medium for the transmission of signals. 

  • We also find that high-speed optical fibres rely on an electrical signal at each end of the line. Without electricity, communication would reduce to letters, flag-waving, lighting fires, and shouting at each other. 

So, why is electricity important?

None of the electricity-free methods is as flexible and flawless as any that we are used to today. For instance, industry manufacturing relies on electricity to drive virtually every moving part in a factory. 

Materials like saws, cutters, conveyor belts, furnaces, chillers - whatever the process be, electricity are involved in all places. 

  • Entertainment: The MP3 player, the portable battery-powered radio, memory stick are all accepted as core parts of our day-to-day lives; all depend on electricity to operate, whether connected to a mains or a power source like a battery, they all use electricity. The list is by no means exhaustive. 


Uses of Electricity in Our Daily Life

We use electricity in all walks of life, some of the uses of electrical energy that are methods to counteract environmental pollution are discussed below:

  1. Residential Uses- Various household appliances and objects that use electricity range from basic items to advanced ones. These include small household items, like a coffee maker, dishwasher, and microwave to the big electrical appliances, like air conditioning units, refrigerators, electric heaters, washers, dryers, etc. In the nutshell, the whole lighting system of your house relies on electricity. 


  1. Transportation System: As per the latest information, the global transportation system depends entirely on the use of electrical energy, be it travelling from one place to another or even communicating around the world is only possible due to electricity. Electricity is massively used by the public through electric vehicles (electric scooters, e-rickshaw). 

Electricity is used to charge vehicles’ batteries. Metros work as an alternative to counteract the railway systems reliant on fuel. 


  1. Industrial Uses: In today’s era, the industrial sector is a vast electricity consumer. 

Without the use of electricity, it would have been a dream to run factories, industrial units, manufacturing processes, and other diverse ranges of activities. 

It is observed that sudden power shutdowns cause severe financial losses to companies that rely on these factories and industrial units. Recently, a rapid rise has been seen in industrial electricity consumption, and it is expected to increase further over the coming years. 

Thus, several industries are working to establish their power plants, so they don’t have to outsource electricity. This way, they are in a better position to cut their utility bills substantially; however, the percentage for industrial usage of electricity varies from country to country.


  1. Commercial Usage: Many commercial buildings like workplaces, hospitals, education centres, restaurants, shopping malls, government properties, police stations, etc use electricity. 

There are a few sub-sectors under the commercial sector that require a limitless supply of electricity, such as hospitals and medical facilities, etc.


How to Measure Electricity?

Electricity is calculated in terms of power which is expressed in the form of watts. The SI unit of power is expressed in watts which are named after the scientist James Watt who is the inventor of the steam engine.


What is Electric Power?

Electric power is the power produced by converting one form of energy to another. Electric power is actually based on the flow of electric charge, that is, current or the potential of charge to deliver energy, that is, voltage. Any combination of current and voltage values results in power.


Applications of Electricity - At A Glance

Electricity is a very powerful innovation of science. Electricity is widely used in all sectors like entertainment, engineering, healthcare, transport and communication, household, outdoors, office, commercial, space, and fuel. The ways in which electricity is used in these fields are:

2. Is Electricity a Primary or Secondary Source of Energy? Is it a Renewable or Non-Renewable Source?

Electricity is a secondary source of energy because we get electrical energy by converting primary sources of energy, like, natural gas, nuclear energy, solar energy, and wind energy into electric power


Electricity is referred to as an energy carrier, which means it can be converted to other forms, such as mechanical energy of the turbine is converted into electricity or heat energy to rotate the turbine for generating electricity. However, electricity is neither renewable nor non-renewable. Therefore, electricity is a secondary source of energy though it cannot be classified into renewable or non-renewable sources of energy. 

3. Why is Energy-Saving Important?

There is a need to use energy-saving strategies to prevent energy wastage. Also, there is a need to introduce reliable energy alternatives to provide a continuous supply of electricity to all the major sectors of the country. The various reasons due to which it is very important for us to save energy are:

  • We need to reduce energy consumption in order to limit the emission of carbon into the environment. Carbon emission is a very important factor that plays a role in climatic change and natural disasters as well.

  • Reduce energy emission, cleans the quality of air that gives a higher quality of life and healthier living

  • Energy emission also conserves the natural environment like lakes, trees, and animals as well for future generations.

  • By saving energy you can also save money and reduce your electricity bills significantly.

4. How Do Electric Eels Use Electricity?

Electric eels use electricity to depart enemies. They can produce a shock of a maximum of 500 volts. Our bodies make use of electricity to communicate, including telling our hearts to keep beating.


Electric eels are freshwater fishes that have the capability to stun their prey by generating electricity. On identifying prey, eels send a signal through the nervous system to the brain. The signals are passed using the electrolyte. Due to the sudden difference in electric potential, an electric current is generated just like a battery. Electric eels can control even the nervous system of the prey due to their electric abilities. This way they control the nervous system and muscles of the prey because of which they can prevent their prey from escaping.
