What are the key differences between AC and DC systems, and where would you use each?

What they want to know is if you understand the basic principles of AC and DC systems and can apply this knowledge to real-world scenarios. You should explain that AC (alternating current) changes direction periodically, making it suitable for household appliances and long-distance power transmission, while DC (direct current) flows in one direction, ideal for battery-powered devices and electronics.

Example: AC and DC systems differ mainly in the flow of current. AC alternates direction, making it ideal for power distribution, like in homes, where it’s easier to transmit over long distances. In contrast, DC flows steadily and is great for batteries and electronics, such as your smartphone. While AC is efficient for large-scale power, DC has advantages in precision applications, like electric vehicles, due to its stable voltage.
