How do circuits work? How do electric plugs work? Why do some things conduct electricity and some things do not? How does a battery make a phone work? How do lights turn on? Where do electrons go when the electricity is off? How fast is electricity? How do light bulbs work? How does solar power work? How do electric cars work? Why is electricity dangerous? Electrical Engineer Paul Hines answers our questions for the second half of our electricity live call-in program. Hines is a professor at the University of Vermont and co-founder of Packetized Energy.
