65. 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

66. 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. Click on screen to continue
