|Consider the following statements
|1. Witricity is a technique that can deliver energy to devices such as laptop, computer without the need of wire.
|2. Witricity is able to make a 60 W light bulb glow from a distance of 12 meters. Which of the statements given above is/are correct?
A) Only 1
B) Only 2
C) Both 1 and 2
D) neither 1 nor 2
Correct Answer: C
Solution :[c] WiTricity is an American engineering company that manufactures devices for wireless energy transfer using resonant energy transfer based on oscillating magnetic fields. WiTricity is based on strong coupling between electromagnetic resonant objects to transfer energy wirelessly between them. This differs from other methods like simple induction, microwaves, or air ionization. The system consists of transmitters and receivers that contain magnetic loop antennas critically tuned to the same frequency.
