Chapter 31: AC Circuits

Alternating Current (AC) circuits are circuits where the current and the voltage vary sinusoidally in time (in comparison with DC circuits where the voltage and current are constant). AC is the type of current you get from wall outlets; the current switches direction 60 times a second (60 Hz current). With AC, we begin the study of circuits with non-linear circuit elements such as capacitors, inductors and transformers, which are the back-bone of analog and power electronics.
