1. An electrical circuit contains a capacitor of 51 picofarads and a resistor of 0 ohms. If the capacitor is fully charged, and then the voltage is interrupted, in how much time will about 95% of its charge be transferred to the resistor? Show your calculations.

2. Referring to Question 1 above, if the resistor is a piece of some unknown substance 12.2 meters long with a cross-sectional area of one square meter, is that substance likely to be a conductor, semiconductor, or insulator? Show your calculations, explain your reasoning, and cite any references you use.

3. Make question about the action potential of the human nervous system and a current source of 12.2 amperes. Then answer it. (you can use resistance like V=RI)
