The Basics of Wireless Charging
Wireless charging, also known as inductive charging, is a technology that allows devices to be charged without the need for physical cables. This is achieved through the use of electromagnetic fields, which transfer energy between two devices: the transmitter and the receiver. The transmitter, usually a charging pad or base, converts alternating current (AC) to direct current (DC) and transmits it wirelessly to the receiver, which is typically a device such as a smartphone or watch.
Wireless charging is based on the principle of electromagnetic induction, which was first discovered by Michael Faraday in 1831. This principle states that an electric current flowing through a coil of wire will generate a magnetic field around the coil. If another coil is placed within this magnetic field, it will induce an electric current in the second coil.
