Wimshurst Machine is used in the experiment of electrostatics to get a lot of charge and high voltage about tens of thousands of volts), in combination with other instruments for experiments about charge distribution on conductor surface, power line or electrostatic field, point discharge and discharge of vacuum tube. Itself can also be used for a series of experiments, such as electrostatic induction, spark discharge, point discharge and capacitor (refer to the Leyden jar on generator) capacitance change and so on.

This Portable Hand Crank Generator can be utilized with almost any experiment requiring up to 12-volt DC current, and functions by way of a hand-crank. It is housed in tough clear plastic, allowing the user to view the unit's mechanisms in real-time. This unit is not only functional but also costs about half the price of similar models. This generator can also be used as a hand generated flashlight due to the mounted lamp on the end and the binding post can be used to connect an outside electrical circuit. A great introduction to the concept of motors and generators; makes an excellent gift or addition to the classroom.
