网页12.1 AC Sources. In Chapter 10 we learned that changing magnetic flux can induce an emf according to Faraday’s law of induction. In particular, if a coil rotates in the presence of a magnetic field, the induced emf varies sinusoidally with time and leads to an alternating current (AC), and provides a source of AC power.
15.2: AC Sources - Physics LibreTexts
网页An ac is produced by an alternating emf, which is generated in a power plant, as described in Induced Electric Fields. If the ac source varies periodically, particularly sinusoidally, the circuit is known as an ac circuit. Examples include the commercial and residential power that serves so many of our needs.
15.8: Alternating-Current Circuits (Summary) - Physics LibreTexts
网页Alternating current (ac) refers to systems in which the source voltage varies periodically, particularly sinusoidally. The voltage source of an ac system puts out a voltage that is calculated from the time, the peak voltage, and the angular frequency.

Some Examples with AC Circuits | Complex Numbers
网页Some Examples with AC Circuits. Let’s connect three AC voltage sources in series and use complex numbers to determine additive voltages. All the rules and laws learned in the study of DC circuits apply to AC circuits as well (Ohm’s Law, Kirchhoff’s Laws, network analysis methods), with the exception of power calculations (Joule’s Law).
AC Voltage Source - Implement sinusoidal voltage source
网页The AC Voltage Source block implements an ideal AC voltage source. The generated voltage U is described by the following relationship: U = A sin (ω t + ϕ), ω = 2 π f, ϕ = Phase in radians. Negative values are allowed for amplitude and phase. A frequency of 0 and phase equal to 90 degrees specify a DC voltage source.

AC Waveform and AC Circuit Theory - Basic Electronics Tutorials …
网页The AC waveform used the most in circuit theory is that of the sinusoidal waveform or sine wave. A periodic AC waveform in the form of a voltage source produces an EMF whose polarity reverses at regular intervals with the time required to complete one full reversal being known as the waveforms period.
