Electricity 201 – DC, AC, Batteries, and Transformers. How does electricity work in electronics and the grid? DIRECT CURRENT or DC is similar to the normal flow of water in a hose – it flows in one direction, from the source to the end. Historically, DC was originally championed by Thomas Edison in the famous Current Wars of the late 1800s. DC lost the war for the grid but it has found an ...

propellers called turbines. These turbines spin coils of wire between magnets to produce electricity. Hydro powered systems also make use of turbines to generate electrical power; however, they do so by using the energy in moving water to spin the turbines. Water has kinetic energy when it flows from higher elevations to lower elevations.
