INTRODUCTION
In our present electricity generation system we waste more then half of its resources .
The main reason for power loss is resistance of wire used for grid .
Wireless electrical transmission as the name shows is the transmission of electrical energy without wires to any place on the earth .
INDUCTION COUPLING
Here transfer of energy takes place by electromagnetic coupling through a process called mutual induction .
This method works only when receiver is in close proximity to the transmitter .
APPLICATIONS :-Wi-power technology .
Electric toothbrush.
Electromegnatic card reader.
RESONANT INDUCTIVE COUPLING
RIC function on the concept that if you make two resonant objects of same resonant frequency tends to exchange energy efficiently , while interacting with extraneous off resonant objects .
Transmission range for this method is nearly 5-10 meters .
MICROWAVE POWER TRANSMISSION
Microwave transmission refers to the technology of transmitting information or power by the use of microwaves waves .
