Witricity
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.
In cell phones signals are sent in the form of micro waves whereas in this mode of transition electricity is transferred in the form of magnetic rays.
These rays are not harmful to humans.
The transfer of energy is mid range compared to direct transmission
Need of Witricity
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, witricity would be useful for many applications as these things need mid range energy.
Working principle of Witricity
Witricity 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 i.e, omnidirectional
Most common things in our surroundings do not interact with these magnetic fields and thus not harmful to other living beings
Significant decluttering of office space
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.
