Alternating Current

This topic deals with the application of electromagnetic induction. It explains the AC generator with elements associated with it. It discusses the generation of alternating emf and mentions the hydroelectric, thermal and nuclear power generators.

In the topic, we will learn about alternating current and direct current. It also explains the utility of alternating current in comparison to the direct current.

This topic discusses the instantaneous, peak, mean, and RMS values of alternating current and voltage. It identifies the values for one cycle and for half cycle.

The topic covers simple AC circuits, electrical reactance and impedance. It explains the different types of AC circuits and also the concepts of inductive reactance and capacitive reactance in detail.

This topic discusses the circuits containing inductance, capacitance and resistance in series (L-C-R series circuit). Further, it explains the impedance triangle and phasor diagram.

This topic discusses the power in AC circuits. It consists of circuits containing pure resistance only and circuits containing both inductance and resistance. Further, it also helps us find the wattless current.

In this topic, we will learn about LC oscillations in detail with diagrams. It explains the reason for unrealistic LC oscillations. It also discusses the analogies between mechanical and electrical quantities.
