Wimshurst Machine, Superior
This traditional electrostatic charge generator consists of two parallel transparent discs supported on rigid uprights. Each disc has a number of radial aluminium segments and are driven in opposite directions by hand wheel and belt. The electrostatic charge on aluminium segments is collected by combs mounted on either end of the discs and stored in the two leyden jars. When the potential difference between the jars is sufficiently high. A spark will flow between the adjustable discharging spheres.

Conductivity Meter
Lab EquipmentsA simple apparatus for testing the electrical conductivity of liquids. Connect the apparatus to the main supply and place the electrodes in the liquid used for testing. A strong conductor is a material that will let electric charges to flow through it very easy
and therefore the bulb of conductivity meter glows brightly. The weak conductors allow electric charges to flow through it slowly and therefore the bulb of conductivity meter glows dimly. The bad conductors do not allow electric charges to flow through it
and therefore the bulb of conductivity meter does not glow at all. Bulb provided is large and bright enough to be seen by the entire class. The conductivity meter includes a clamp on the back for attaching to a support stand. Instructions and appliance bulb are also included.
