How are AC voltage sources depicted in a TPC schematic?

In TPC schematics, AC voltage sources are depicted using a sine wave symbol or an alternating current icon because these representations effectively communicate the nature of alternating current. The sine wave is a fundamental representation of AC voltage because it visually reflects the smooth, periodic oscillations of voltage over time. This form of representation helps anyone reading the schematic to easily identify the voltage source as alternating current, which is essential for understanding the functionality of the circuit being analyzed.

Other symbols, such as a rectangular wave icon or jagged lines, do not accurately represent the characteristics of standard AC voltage sources. The rectangular wave could indicate a different type of signal, like a square wave, while jagged lines may imply rapid fluctuations rather than the smooth sinusoidal nature of AC voltage. Therefore, using a sine wave or an alternating current icon is the most effective and widely recognized means of depicting AC sources in schematics.
