Summary

Description
English: Schematic view of a classical Van De Graaff generator.
  1. hollow metallic sphere (with positive charges)
  2. electrode connected to the sphere, a brush ensures contact between the electrode and the belt
  3. upper roller (Plexiglass)
  4. side of the belt with positive charges
  5. opposite side of the belt with negative charges
  6. lower roller (metal)
  7. lower electrode (ground)
  8. spherical device with negative charges, used to discharge the main sphere
  9. spark produced by the difference of potentials
Català: Esquema d'un generador de Van de Graaff.
  1. Esfera metàl·lica buida (amb càrrega positiva)
  2. Elèctrode connectat a l'esfera, un raspall molt pròxim (però no en contacte) a l'elèctrode i la corretja
  3. Rodament superior (per exemple de plexiglàs)
  4. Costat de la corretja amb càrrega positiva
  5. Costat oposat de la corretja amb càrrega negativa
  6. Rodament inferior (metall)
  7. Elèctrode inferior (terra)
  8. Dispositiu esfèric amb càrrega negativa, utilitzat per a descarregar l'esfera principal
  9. Espurna produïda per la diferència de potencial
Deutsch: Van-de-Graaff-Generator schematisch
  1. metallische Hohlkugel (trägt positive Ladung)
  2. oberer Abnahmekamm (o. Bürste), mit kleinem Abstand zum Band (jedoch ohne Berührung)
  3. obere Umlenkrolle (Plexiglass)
  4. positiv geladene Bandseite (Band dielektrisch)
  5. negativ geladene Bandseite
  6. untere Umlenkrolle (Metall)
  7. unterer Abnahmekamm (Erde, Gegenelektrode f. neg. Ladung)
  8. Kugel mit negativer Ladung (zur Entladung der Hauptkugel)
  9. Funkenstrecke (mgl. Lichtbogen bei der Entladung)

  1. Esfera metálica hueca (con carga positiva)
  2. Electrodo conectado a la esfera, un cepillo muy próximo (pero no en contacto) al electrodo y la correa
  3. Rodamiento superior (por ejemplo en plexiglás)
  4. Lado de la correa con carga positiva
  5. Lado opuesto de la correa con carga negativa
  6. Rodamiento inferior (metal)
  7. Electrodo inferior (tierra)
  8. Dispositivo esférico con carga negativa, utilizado para descargar la esfera principal
  9. Chispa producida por la diferencia de potencial

In the correction, on the right side the belt is neutral and the negative charges stores in the acrylic cylinder repel the negative charges to the ground.
