Learning Goal: To understand the concepts explaining the operation of transformers.One of the advantages of alternating current (ac) over direct current (dc) is the ease with which voltage levels can be increased or decreased. Such a need is alwayspresent due to the practical requirements of energy distribution. On the one hand, the voltage supplied to the end users must be reasonably low for safety reasons(depending on the country, that voltage may be 110 volts, 220 volts, or some other value...

Resonant wireless charging is an emerging technology where a powered transmitting circuit induces a current in a receiving circuit by the magnetic interaction between the circuits' inductors. Similar to how transformers work, what makes this process unique is that the receiving circuit can be several centimeters to a few meters away from the transmitting circuit, depending on the system. This induction with distance works only when both circuits, which can be treated like effective LRC circuits, operate at the same...
