Title:
    WIMSHURST MACHINE
Description:
    Induced charge on plates is transferred to combs and then to discharging electrode.
Equipment:
    1. Wimshurst Machine
Procedure:
    1. Set 2.5 cm gap with discharging electrodes.
    2. Set small electrodes together (contact).
    3. Crank handle to generate a spark between the upper electrodes.

    Caution: to discharge the Wimshurst, carefully swing the discharge arms to the middle of the apparatus until they touch.

    Note -- breakdown voltage = 30,000 v/cm
