I have a very limited knowledge of electrical engineering that almost entirely revolves around music equipment. From everything that I’ve seen, music equipment ends up converting the AC power to DC power right at the power entry point (or at least soon after). It appears they’re converting AC power to a higher voltage and current DC power. Is the only real advantage of AC power to pump more power over a line to where devices will then manipulate it to what they need in DC? Are there any common household items that actually fully operate off of AC power or does everything convert to DC at some point?

It was chosen because it’s easy to multiply and divide the voltage with transformers. The voltage can be raised very high to transmit over long distances with minimal loss to cable resistance.. then dropped back down for distribution in neighborhoods, then again to feed homes.
