AC is produced by generators in power stations and can be found in homes, radio equipment, car alternators, and even synthesizers. AC voltage has several advantages over DC voltage (generation and transmission, transformer voltage increase / decrease, electromagnetic emissions, etc.), but the analysis can be more complex, involving imaginary numbers, phasor diagrams, Laplace transforms, and even second-order differentiation equations (oscillators).
