WIRELESS ELECTRICITY TRANSMISSION

What is wireless electricity?? Transfer of electricity without using connections between input and load is termed as wireless electricity.

This is not like wireless transmission of signals which we used in the cell phones.

Electricity is transferred in the form of magnetic rays.

The transfer of energy is mid range compared to direct transmission.

Need of wireless electricity transmission Now-a-days there is a rapid increase of electronic

goods like cell phones ,laptops ,I-pods etc., which rely on the chemical storage of energy by the battery which need to be recharged frequently .As these are becoming daily needs to the present generation wireless energy transfer i.e, this would be useful for many applications as these things need mid range energy.

Working principle:Wireless electricity works on the principle of mutual

induction between the two coils.There are two copper coils arranged one at the sender end

and other at the receiver end .The first coil is attached to the power source while the second coil to the light bulb.

When the power is switched on the first coil converts the electricity into magnetic field ,which is oscillating at a particular frequency i.e, AC source.

The second coil at the receiver end converts the magnetic field into electricity .The surrounding environment is unaffected.

Advantages:

An advantage is that we can produce electricity anywhere without wires

The power can be delivered in any direction. No need for meter rooms and electrical closets. Reduction of e-waste by eliminating the need for power cords Need more light in your office, no need for electrician. Simply place the

lamp where ever you need it. These rays are not harmful for human being.

The flux condition should satisfy certain conditions, if not no power supply takes place.

There is a lose of power transmission if there is a strong Ferro magnetic substance.

Need for standardization and adaptation. So no overheating occurs because of different voltages.

Possibility of “energy theft”. Wi Fi, someone can be using your internet or your power.

Disadvantages:

World in our future
