1. If charges flow very slowly through a metal, why does it not require several hours for a light to come on when you throw a switch? 2. Newspaper articles often contain statements such as "10 000 volts of electricity surged through the victim's body." What is wrong with this statement? 3. Why is it possible for a bird to sit on a high-voltage wire without being electrocuted? 4. Referring to the figure below, describe what happens to the lightbulb after the switch is closed. Assume the capacitor has a large capacitance and is initially uncharged. Also assume the light illuminates when connected directly across the battery terminals.
