Topic 8
Electric Charges, Fields, and Gauss's Law
A lightning bolt hits a car. Inside, the people feel nothing at all. Why? The metal shell around them is a conductor. Charge races over its outside surface…

Topic 9
Electric Potential
Look at these numbers. A small battery says one point five volts. A car battery says twelve. A high-voltage transmission line carries four hundred thousand. A…

Topic 10
Conductors and Capacitors
A plane is struck by lightning about once a year, and the people inside feel almost nothing. A car in a thunderstorm is one of the safest places to sit. Why?…

Topic 12
Magnetic Fields and Electromagnetism
Look north on a clear winter night, far enough north, and the sky glows green. Those lights are switched on by a magnetic field. The Sun throws charged…

Topic 13
Electromagnetic Induction
Almost every watt of electricity you have ever used began the same way, with a magnet and a coil of wire moving past each other. No fuel, no burning: only…
