The top pan was repulsed by the lower pans, which were
all electrically negative.
F 200
The reason that we stood on a bucket.
F 300
To avoid grounding.
F 300
The reason that we stayed away from the gas jets,
radiators, and touching others
F 400
Grounding (or static discharge)
F 400
The reason that it is better to touch the metal rod with more of your hand/arm, rather than
just using your finger tip.
F 500
The charge is spread out and less concentrated.
F 500
The Final Jeopardy Category is:
Van de Graff
Please record your wager.
Click on screen to begin
When we were all in a circle, the first half of the circle received little or no shock, yet the last half received a much greater shock
than if they were alone. Explain.

The charge built up on the circle was enough to fully charge 5-20 people (depending on the class),
so when the circuit was closed, 5-20 people worth of voltage was
delivered, rather than one persons charge.
