This video explains electricity as the flow of atomic particles called
electrons. Animations demonstrate electron flow. Batteries are described as chemical devices designed to create electron flow. Key words include: electrons, positive charge, neg...ative charge, current, amp, voltage, short circuit, and circuit. (5:16)

This video ten minute video explores voltage. The video primarily differentiates electric potential and electrical potential energy. Electric
potential energy is the amount of work that is needed to move that
particle from one spot to another. Th...e video features animation and a spokesperson.

In this interactive simulation adapted from the University of Colorado's Physics Education Technology project, learn about the relationship between electric current, voltage, and resistance. Known as Ohm's law, this relationship can be described by t...he equation V = I x R. In this activity, you can adjust the voltage and resistance in a simple circuit to see how the current changes according to Ohm's law.

In this interactive resource adapted from the Wisconsin Online Resource Center, learn how a generator produces alternating current. More specifically, see how slip rings, brushes, an armature loop, and a magnetic field interact to produce single-phas...e alternating current. Animations show how positive and negative voltages are induced into the armature loop as it rotates through the magnetic field, and how the polarity of the voltage changes periodically, visualized as a sine wave.
