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.
