Electrical

My You Tube channel is here.

Basic Electrical

Current: Current is the flow of electron.

Battery: Battery is a storage of electron.

Important factors of Electric energy

1.Easily covert-able
Electric energy can easily converted into other form.
Example:If we flow current through a wire we can easily found heat.

2.Control
Electric machine can easily start and off by pushing a switch.

3.Transport

Electric energy can easily transport from one place to another through

a wire.

4.Low cost

Electric energy is cheaper than other forms of energy.

5.Suitable

Electric do not create any smoke or fums.

Energy source

1.Sun

Sun is a open source of electric energy. The heat of sun can easily
converted into electric energy.
Advantage:
Low maintenance cost.
Open source.
Keep environment safe.
Disadvantage
Requires a large space.
Initial cost high.

2.Water

Water can converted into electrical energy using turbine.
Turbine drives alternator and produce electric energy from mechanical energy.
Advantage
Low maintenance cost.
Reliable.

3. Fuel

Figure: IC engine.

Fuel converted into mechanical energy by using Steam engine, internal combustion
engine.

4.Nuclear energy

Figure: Fusion.
Nuclear energy produce large number of current.
It produce current by fusions of uranium and other fusion-able material.

Power station

1.Steam power generation

 A power station that produces electrical energy from heat energy of coal is known as steam power station.

Steam turbine runs the alternator which convert mechanical energy of the turbine into electrical energy. This type of power station situated where coal and water are available.

Advantage

The fuel used it is cheap.

Less initial cost comparing other generating station.

It can be installed at a place where coal exists. The coal can be transported to the site(plant) by rail or road.

The cost of generation is less then diesel power station.                                                                                                             

Disadvantage

It pollutes the atmosphere due to the production of large amount of smoke and fumes.

It is costlier in running cost as compared to hydroelectric plant.
