AC (Alternating Current) and DC (Direct Current) are two fundamental types of electrical current with distinct characteristics and applications. DC current flows in one direction and powers devices like phones, laptops, and cars, developed by Thomas Edison. In contrast, AC current has electrons that vibrate back and forth 60 times per second without net movement, developed by Nikola Tesla. AC current is more efficient for long-distance power transmission because it can be easily transformed to higher voltages for reduced energy loss during transmission. This efficiency means cities can use fewer power plants compared to DC systems, which would require power plants on every street corner. Electricity is typically transmitted through AC current and then converted to DC current for use in electronic devices and specialized infrastructure.
