AC and DC power differ in direction, usage, and efficiency. Learn the basics of how alternating and direct current work and where each is used.

Batteries are a part of our everyday life, and power everything from phones to gaming handhelds to laptops, but do those batteries use AC or DC current?

However, electric vehicle batteries require a direct current supply for charging. Every EV, therefore, is outfitted with an inverter to convert AC to DC, which can in turn charge the EV’s battery.
