PIRA Classification: 5C10.30

Description: A large cylindrical capacitor is connected to an electroscope. When a 2000 V power supply is switched on and the leads brought to the capacitor, the cylinders will charge and the electroscope will deflect slightly. When the power supply is removed from the circuit and the cylinders are moved apart, the electroscope will deflect even more.

Special Instructions: Make sure the inner cylinder is fully inside the outer cylinder.

Condition: Good

Setup time: 2 minutes

Safety Issues: Touching the charged capacitor can lead to a shock.
