SUMMARY
The Van de Graaff generator operates by using a high-voltage power supply to create a strong electric field, which causes dielectric breakdown of air and transfers positive charge to an insulated belt. The power supply continuously replenishes the positive charge on the conductor, despite the apparent discontinuity in the circuit path. The flow of electricity moves from the power supply to the discharge electrode, up the belt to the top-load sphere, and discharges into the air, completing the circuit through the ground connection. This system can be modeled as a capacitor, where the top-load acts as one plate and the ground as the other, resulting in periodic discharges.
