In terms of voltage levels, what is typically observed in AC systems compared to DC systems?

AC systems are distinctive due to their ability to be transformed to different voltage levels efficiently. This capability is primarily made possible by the use of transformers, which provide the flexibility to step voltage levels up or down as needed. This is a crucial advantage in electrical distribution systems because it allows for the transmission of electricity over long distances at higher voltages, which reduces losses due to resistance in the wires. Once the electricity reaches its destination, it can be stepped down to a safer, usable voltage for residential or commercial applications.

The ability to easily adjust voltage levels makes AC systems particularly suited for large-scale power distribution and ensures that the infrastructure can accommodate varying energy demands without sacrificing efficiency or performance. This characteristic is one of the key reasons why AC has been widely adopted for power transmission and distribution systems around the world.
