Corona discharge. A Van de Graaff generator uses a moving belt and the triboelectric effect to accumulate electric charges on a hollow metal globe and create very high electric potentials. When a grounded ball is brought close to the charged globe, the air between them undergoes electrical breakdown and ionization, resulting in a visible corona discharge spark. | |
