Code Number: 5C20.10

Demo Title: Gang Capacitors / Rotary Capacitors

Condition: Good

Principle: Capacitance dependence on plate area.

Area of Study: Electricity & Magnetism

Equipment: 

Gang or rotary capacitors, Capacitance meter.

Procedure:

Hook the gang capacitors to a capacitance meter and observe the change of capacitance as the overlap of the plates is changed.
