Alternating current is used in many countries because of the fact that it can carry more volts of power with fewer amps as well as the discovery of transformers which only work because AC creates a flux that induces a current in the other wire and allow for more current to be carried in the wires and stepped down to go into houses.

Alternating current is preferred because it can be easily transformed to higher or lower voltages using Transformers, which makes it more practical for long-distance transmission. AC is also safer for use in homes and buildings due to its ability to be easily controlled and shut off in case of emergencies. Lastly, AC is more efficient for powering various types of electrical devices and machinery compared to direct current.
