Wireless current transmission is the transfer of electrical power from a power source to an electronic device without the use of physical wires or cables. It is achieved through the use of electromagnetic fields.
Wireless current transmission works by using two coils - a transmitter coil and a receiver coil. An alternating current is passed through the transmitter coil, creating an electromagnetic field. This field induces a current in the receiver coil, which can then be used to power the electronic device.
Wireless current transmission eliminates the need for physical wires and cables, making it more convenient and efficient. It also allows for devices to be charged or powered without the need for direct contact, reducing wear and tear on charging ports and cables.
One of the main limitations of wireless current transmission is the distance over which it can effectively transmit power. The strength of the electromagnetic field weakens over distance, so the devices must be relatively close to each other. Additionally, the efficiency of wireless current transmission is lower than that of traditional wired methods.
Wireless current transmission is generally considered safe, as the electromagnetic fields used are typically low power and do not pose a health risk. However, it is important to follow safety guidelines and use properly designed and tested equipment to prevent any potential hazards.
