Electric Field Mapping
Electrostatics relates charge distributions, lines of equipotential (constant potential), and electric field lines
under static conditions (where there are no moving charges). Electric charges are the source of the elec

Electrical Energy
In this experiment, you will study a small, inexpensive electric motor used as a crude elevator. You will measure the current through, and
voltage across, a motor as it lifts a small mass. If you know the current and voltage

Capacitors in Series and Parallel
If a potential difference V is established between the two conductors of a given capacitor, they
acquire opposite charges Q and +Q (Q=+Q). It turns out that the electric charge Q is
