Van de Graaff generator
Van de Graaff generatorGenerates very high DC voltages, but is safe to use due to low output current.
The generator features a conducting sphere with a diameter of 220 mm.
The sphere is fitted with a Ø 4 mm socket for connecting other equipment via a lead.
Voltaic pile
Voltaic pileThe voltaic pile was the first galvanic battery. Invented by Alessandro Volta in 1800, it facilitated research into electrical currents. This model closely resembles the original design, but using more modern materials. Plexiglas replaces the original wooden parts.
