Electric Currents and Fields

Posted on January 1, 2011 by Merrill Falk

Students will observe that the magnetic field created by a coil of wire is perpendicular to the plane of the coil. They will also see that the field is stronger with more current, and that the field reverses direction when the current reverses.

Series Circuits

Posted on November 9, 2006 by Merrill Falk

Circuits Series Circuits Several properties of a series circuit will be demonstrated in this experiment. The primary concepts to be covered are: 1. Lamps in series reduce current flow. 2. Lamps in series increase the total resistance of the circuit. 3. The voltage across each bulb in a series circuit decreases as the number of bulbs in the circuit increases.
