Cordless charging is generally referred to as wireless battery charging. It is a method for transferring electrical charges from a charger to the battery without the need of a physical wire.
Working Principle:It is based on the inductive principle in which magnetic field transfers energy from one device to another device. This principle is widely used to power many portable devices such as mobile phones and other wireless applications. Its working principle is quite similar to the transformers where primary coil is connected with the electrical supply as a main power source and the secondary coil is induced with electric charge ( in this case, it is a mobile phone).
Advantages: - Wireless charging has the following benefits: -
Disadvantages: - Besides its advantages, it has some disadvantages: -
