1. A Van de Graaf generator is capable of generating up to 150 kVolts, yet a person may safely touch one. Your hair will stand straight up, but you will not be harmed. Describe how it is that such a high voltage can be made relatively harmless.

2. Explain why some people who contact 120 Volts are killed, while most are not.

3. You generally cannot control the amplitude of the voltage you may be working with, nor the ampacity (current capability) of the source. However, you can control your resistance. Tell what all these have to do with Ohm's Law and general safety practices.
