WIRELESS ELECTRICITY-EXPLAINED

Movement of electrons (current) in free space without using any proper conduction path between two electronic devices is referred to as wireless electricity.Long before it is a dream but after a few years it will come true.

• Everyone knew that conductor has free valence electrons, by applying proper voltage (nothing but force) these electrons move and results current(flow of electrons).

1.Actually the concept of wireless electricity has started with faraday's law.

It states that whenever a conductor is placed in magnetic field(time changing) an induced emf(electro motive force) or voltage is induced in another conductor.This is considered as base for wireless electricity. Without any proper conduction path,this induced emf will results to move electrons in another conductor.This concept resulted to discover transformer.With the transformer we are able to alter voltage from a high valve(received from station)to a value required for home appliances.This is beginning for wireless electricity.

2.Second thing I would consider is from the basics of antenna. Actually antenna is an interface between free space and transmission line that converts V/I waves into E/H waves at the transmitter and viceversa at the receiver.HOW? When a voltage(V/I) is fed at the input, due to electric field(electrons) and magnetic field(as these electrons are moving),E/H waves are released into medium, this conversion V/I into E/H process is called radiation and at the receiver E/H is converted back  to its V/I form, this process is called induction.

By adopting both radiation and induction techniques we can transmit electricity without proper conduction path between two devices.

Conclusion:From first technique we need a strong magnetic field between two wireless devices and from second technique we need an antenna for wireless transfer of electricity.
