Hundreds of years ago, Nikola Tesla invented the wireless transmission of electricity. He was able to transmit AC power over short distances. Thus, the era of wireless technology has begun by his invention.

How did Tesla transmit alternating current by means of wireless network?
In his quest for wireless energy, he had conducted several tests and finally invented the revolutionary element called the Tesla coil. It is nothing but a radio frequency oscillator that uses a resonant transformer to generate high frequency AC voltages. Tesla coil generates high voltages at low currents.
Nikola Tesla used this coil as the power source to light up an array of fluorescent lamps at a short distance from the source. But he could not complete his experiments over long distance of electricity transmission. But the Tesla coil finds applications even now.
Pros and Cons of Tesla Coil
Tesla coil has no complexity circuits hence find applications in vacuum and welding systems, educational demonstrations, and entertainment lightings. The high voltage generated from Tesla coil can harm human if proper care has not been made. The expense of the production is significantly high and also time-consuming.
Basic principle of wireless electricity and applications
Without wires, the electricity transmission is by means of inductive coupling and electromagnetism. The circuitry zone comprises of two separate coils; one in the transmitter area and other in the receiver area. The positioning of the transmitter is near to the receiver. When alternating current passes through the transmitter coil, there develops a magnetic field in the transmitter which in turn generates a voltage in the receiver area. This principle is made used in electric toothbrush and mobile charging pads.
Isn't it the long-distance wireless transmission of electricity possible at all?
Wireless electricity is one of the ongoing conceptions that is being rapidly developing. Various studies and investigations are going on based on the electromagnetic induction principle acknowledging Tesla's inventions. Of course, it is a considerable challenge to transmit electricity without metal contacts over long distances.
Like as mentioned before, the exposure of generated wireless voltage to the human body is highly dangerous if proper measures had not been made of. Of course, it will be time-consuming to separate the wireless area of generating and transmitting sections. And above all the expense and complexity of employing inductive coupling and electromagnetism for the long-distance wireless energy transfer is significantly high.
