What Is Electricity/USES OF ELECTRICITY

Electricity, It  is a form of energy formed from the existence of charged particles (like electrons and protons). Electricity plays an important role  in this modern life style. In this time a person cannot leave without electricity. It is required for all  basic purposes  in daily life.

Uses of electricity or electric current

Electricity  is a very important and useful  form of energy it is used to run  almost all he appliances of home. It is used for fan, ac cooolers, freezer and many more things.All the modern technology cannot run without electricity like laptop, mobile etc. It is used in large scale industries to run big machines.     

Now the question arives that what is electric current , The flow of electrical energy  or electricity is known as electric current. It is measured in amperes and it basically flows from wires known as conductor. Any thing which allow the current to flow from it is known as contuctor.  There is a reverse of it also which works opposite of conductor known as insulator, the materials which does not allow the current to flow from it is known a insulator.

Use of  insulator and conductors

Conductors are basically used to transport the current from one place to another place.  It is used in homes to provide current to all electrical appliances present in the home.

All the conductors are having some resistance.

Resistance, the tandency to oppose the current is known as resistance. A conductor having some appreciable resistance is known as  resistor. A resistor is also used in homes to prevent the lose of electricity and  making the risk of shock less.

HOW THE ELECTRICITY FORM

Electricity is formed in many places by various methods some of them are like in power stations they converts fuels into electricity.

 

59% of  electricity is formed from   Coal  in various power stations.

The process used in power stations is they burns the coal and gas to make the water heat  and when the water is heated it changes into steam. The steam formed is compressed  into a very high pressure and this high pressure steam hits the turbine and rotate it. By the rotation of turbine the generator produce electricity.

17% of electricity is generated from hydro electric power stations

In this the eletricity is produced with the help of water and big dams. It is the developed process to generate the electricity. It was very  developed from the time when it is made.

It is produced when the fast flowing water is relesed  on the turbine shaft to rotate it and the turbine contain the dynamo and when the turbine rotates from the power of fast flowing water  the dynamo also rotates mechanical energy is converted into electricity and hence the eletricity is formed.

 

By thermo electric generator :

In this phenomena the heat energy is directly converted into electrical energy by the use of thermo electric generator. But it is high coastly  and less efficient. It works as a heat engines. It does not contains any moving parts.This thermoelectric power plant can be used in big dams where the heat produced are wasting can be converted into electrical energy by the thermo electric  generator.

So we have discuss that how electricity is generated and the uses of it from that we have noticed that the electricity is very important for daily life so we should save it. Electricity can be saved in many ways some of them are-

i)We should always keep any electrical gadget or electrical appliances unplug because they can consume the electricity when we cut the connection also or turn off the switch of that gadget or appliance than also it consumes electricity so always keep the electrical appliances unplug.

ii)Use less voltage  comsuming appliances USES OF ELECTRICITY 

All the appliances bassically works on electricity like in home  all apliances works at a fix energy.

Ex – Tubelight,  it requires 36 watts electricity at a constant rate to operate there are many varities in it  like some LED lights operate at 9, 21 watts etc.

Fan – It operates at between 60 to 70 watts electricity  at a constant rate.

Fridge – It is a very heavy power consuming device  like a 160 to 180 litre fridge will take around 200 watts  electricity to start.

Laptop – It is the most useful device in  this modern lifestyle. It mainy takes 50 watts to operate.

Tv – Different types of tv has their different electricity usage rate. Like I am talking about a 45 inch tv it will take around  70 watts electrcity to operate.

Geyser – The standard power at which a geyser works is 1ooo watts

Micrwave oven – The power at which any mivrowave or oven operate is 1500 watts.

So I have given some examples of electrical appliances and the power at which they operateand all ex that I have taken is used  in our daily life so from this we can understand that electricity plays an very important role in this modern lifestyle.
