Electricity Science Shop

Electricity is a form of energy resulting from the existence of charged particles, these days it is incredibly hard to live without it as almost everything uses electricity in some form. We sell excellent electricity and electronics kits and equipment to help parents and children to explore this mysterious energy and learn about the exciting prospects it has for our future.

  1. Wimshurst Electrostatics Machine

    Wimshurst Electrostatics Machine

    The ideal equipment for simple demonstration of electrostatics. No electrical power is required. The unit will quickly generate a charge with regular discharge. Under correct conditions the spark will travel 50mm in air between electrodes. Two plates are supported in two rigid uprights and driven by a belt in the opposite direction. The plates are heavy, high resistance plastic with sectors of aluminium sheet. Two leyden jars (condensers) are made from corning glass and aluminium foil. The apparatus is mounted on a sturdy base for easy use and transportation. 200mm diameter. Learn More
  2. Van de Graaff Generator (Large)

    Van de Graaff Generator (Large)

    The Generator consists of a conducting sphere (the dome) supported by a Plexiglas pillar and a rubber belt driven by an electric motor concealed in the metal base. Static electrical charge is produced by friction between this band and two rollers, one of polythene, the other of Plexiglas. The charge is removed from the belt by a metal gauze and stored in the dome. The electric motor is driven from the mains supply, using a three-wire cable. The base is fitted with a 4mm diameter socket which can be used either for supporting a conducting sphere (fitted with a cranked rod support) or for a wire connection to a separate conducting sphere (fitted on a Plexiglas rod). A dust cover is provided to keep the Van de Graff free from dust when not in use. Learn More
  3. Van de Graaff Generator

    Van de Graaff Generator

    This Van de Graaf Generator is cranked by hand to demonstrate the effects of static electricity. Because you control the amount of electricity produced depending upon how hard and how long you crank, this is a true "hands on" experience for students. Can also be powered by a DC source from a laboratory power supply. Learn More
  4. Smoothing unit

    Smoothing unit

    A smoothing unit for reducing ripple from non-regulated power supplies. Maintains a ripple-free output when high currents are drawn. The unit comprises a lightweight and efficient toroidal 0.1H inductor with a network of 2,200uF capacitors and diodes. With a supply of 12V at 3A, 1% ripple would be typical. Will work without suffering damage even at reverse polarity. Up to 8A at 35V, absolute maximum 40V d.c. (d.c. rectified from 28V a.c). Shrouded sockets accept standard 4mm plugs and shrouded plugs.

  5. Signal Generator and Amplifier

    Signal Generator and Amplifier

    The Signal generator is a robust and reliable instrument that can withstand prolonged short circuit for the output. The earth provided is connected to the physical earth through the power cord; the signal generator output is floating with respect to ground. Learn More
