Series-parallel circuit. The Figure at right shows three impedances; ... Mathematically, imaginary numbers contain a factor of sq root -1, denoted by a "j." So a complex impedance consisting of 3 ohms ...

They also use less wiring than parallel circuits. ... The current in a series circuit depends upon the number of cells. If you make the cells face in the same direction, ...

In this study, we propose a power device configuration that maximizes the inverter efficiency of a pulse-width-controlled high-power wireless power transfer system. Silicon carbide ...
