The key components are electrodes under the wing that run horizontally. There are many of them, but to understand how the airplane flies, you only need to consider the relationship between two. One electrode is thin, like a wire, and thanks to a battery and power converter onboard the plane, that electrode is charged to a whopping 20,000 volts of electricity. Behind that thin electrode, and more towards the back of the plane, is another one—it looks like a tiny wing. That second electrode is charged with negative 20,000 volts, creating a difference of 40,000 volts.
