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, 5-20 people worth of voltage was

delivered, rather than one persons charge.
