PIRA Classification: 5C10.20
Description: A large parallel plate capacitor is connected to an electroscope. When a 3000 V power supply is switched on and the leads brought to the plates, the capacitor will charge and the electroscope will deflect slightly. When the power supply is removed from the circuit and the plates are moved apart, the electroscope will deflect even more.
Special Instructions: Make sure the plates are barely apart (not touching) at beginning of demo.
Condition: Good
Setup time: 2 minutes
Safety Issues: Touching the charged plates can give you a bit of a jolt.
