PIRA Classification: 5C10.30

Description: A cylindrical capacitor, connected to an electroscope, is charged with a 1000 V battery. As the inner cylinder is pulled out from the outer cylinder, the electroscope deflects, indicating an increase in potential difference.

Special Instructions: Touch the battery electrodes to the two cylinders.

Ideally For: Phys 1102, 1202, 1302, 1402

Condition: Good

Setup time: 3 minutes

Safety Issues: Don't short the battery
