WIRELESS POWER TRANSFER: MINI TESLA COIL The mini Tesla coil works when a battery is connected to the circuit. There is a current flow into the base and the transistor is “ON”. In this state, transistor is in conductive state that allow current to start flowing through the primary coil and induces a voltage in the secondary coil. The lower end of the secondary coil becomes negative, pulling down the voltage at the base that act as signal to transistor to switch off. When the transistor switched “OFF”, the current in the primary coil stops and get maximum voltage at secondary coil but in reverse direction. Then the cycle repeats when the coils are discharge and causes a changing of magnetic field that creates an electric potential that compels current to flow. This oscillates happen at a very high frequency which creates an alternating current output on the secondary coil. The secondary wire coil uses electromagnetic induction to convert this magnetic field to an electric potential so high that it can easily break apart the air molecules at its ends and push their electrons in wild arcs. Any high frequency produced electromagnetic waves that cause a fluorescent bulb to glow. The electromagnetic waves excite the gases in the tube, causing them to emit photons (light).

5G: A NEW ERA OF COMMUNICATION The development of mobile communication technologies has restructured the way people communicate. Over years, new technologies have been created so that people will stay connected without any obstacles. People nowadays demand for a better quality of services, more capacity, improved data rate and decreased latency. Significantly, a lot of impactful improvements need to be done to fulfil these demands. From this day, our wireless communication technologies will emerge from the fourth generation (4G) to fifth generation (5G) mobile networks. 5G are supposed to have higher data rate transfer and have better connection between devices. The results documentation shows that 5G are able to deliver data at the rate of minimum 10 Gbps up to 50 Gbps. The connected devices can exchange and perform information without any manual assistance from the humans. It is shown that 5G mobile networks are vital for better communication among people across the globe.
