Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

Inductive Reactance is defined as the opposition to current flow. It is the reaction of the inductor to the changing value of alternating current. To explain further, a back electromotive force (emf) ...

CBSE class 12 Physics chapter wise notes (or key notes) on chapter Alternating Current are available in this article. These key notes are important and very helpful for revision purpose before the ...

Electrical ratings are interdependent. The current through a component depends on the applied voltage (waveform and duty cycle) and the component impedance. The impedance of a component depends on the ...
