Abstract: All of the electronics devices needs power and the power given wirelessly to devices like embedded or real time systems, gets more advantages. The major issue of the consumer products is the short life of battery even in high technology support systems. Many researches are going on with wireless power transfer technology via magnetism, microwaves, resonance etc... One method resonance is covered in this paper.

Keywords: Wireless power transfer technology (WPTT), Resonance, Resonance frequency, Magnetic Coupling.
