An In-Depth Look at AC Schematic Diagrams - elecdiags.com
An AC schematic, also known as an alternating current schematic, is a graphical representation of an electrical circuit that uses alternating current. It is a simplified diagram that shows the connections between various components in the circuit …
AC stands for alternating current – in fact, both the current and the voltage oscillate sinusoidally. What this means for the light bulb filament is that the current reverses direction at regular intervals. In North America, in fact, where the frequency of the alternating voltage is 60 Hz, the current changes direction 120 times every second!
Alternating current - Wikipedia
Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction.
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. The symbol for an AC voltage source is .
What is Alternating Current (AC)? - All About Circuits
AC stands for “Alternating Current,” meaning voltage or current that changes polarity or direction, respectively, over time. AC electromechanical generators, known as alternators , are of simpler construction than DC electromechanical generators.
In an AC circuit, the potential across an element and the current through it both vary with time so that the power dissipated in the element also varies with time. As we shall see, in an AC circuit, there often a phase difference between the potential difference across a circuit element and the current passing through it.
Represent sinusoidally varying voltages / currents through the projection of a vector, with length equal to the amplitude, onto a horizontal axis. Phasor: vector that rotates counterclockwise with constant ω. Diode (rectifier): device that conducts better in full wave rectifier circuit one direction than in the other.
When we work with AC sources, we shall assume that the voltages, the currents, and the charges are all sinusoidal functions of time, with appropriate phases. The voltage or current supplied by an AC source are sinusoidal with time. The voltage or current supplied by an DC source are constant with time. and f is the frequency, expressed in Hertz.

Time and phasor animations are used to explain alternating current (AC) circuits. Impedance, phase relations, resonance and RMS quantities are shown on this resource page from Physclips: a multi-level, multimedia introduction to physics (download the animations on this page).
The relation between current flow in a circuit element and the voltage across the element can be expressed as a relation between the complex numbers that represent the voltage and the current.
