The capacitor stores the same charge for a smaller voltage, implying that it has a larger capacitance because of the dielectric. Another way to understand how a dielectric increases capacitance is to consider its effect on the electric field inside the capacitor. Figure (PageIndex{5})(b) shows the electric field lines with a dielectric in place.
Charge on this equivalent capacitor is the same as the charge on any capacitor in a series combination: That is, all capacitors of a series combination have the same charge. This occurs due to the conservation of charge in the circuit.

on the capacitor due to the series reactor will be of about 4%. If tuning lower, like at the 3.78th harmonic, the voltage rise will be of about 7%. But in any case, the series reactor will never create a very large fundamental voltage rise on the capacitor and a 10% margin on capacitor voltage rating would be sufficient to

Wireless power transfer (WPT) technologies can be categorised in different ways. One method for classifying WPT technologies depends on the range of power delivery: far-field WPT technology and near-field WPT technology. Far-field WPT technology is based on the electromagnetic radiation technique using the microwave, laser or solar satellite.

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
