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. Click on screen to continue
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, people worth of voltage was delivered, rather than one persons charge. Click on screen to continue
