Electricity and Magnetism

5F 15.25 - Bird on a Wire

Demonstrates: Potential difference on a power line.
Description: A "bird" is molded with gun-cotton and "perched" on a nichrome wire. When the two aluminum sections touch both a hot wire and the ground top wire, poof, the bird disappears.

5F 20.50 - Series and Parallel Circuits

Demonstrates: Series and parallel circuits.
Description: One shorting bar, one 150 Watt and three 40 Watt light bulbs can be arranged in various series and parallel combinations to demonstrate current flow and voltage drop as shown by the intensity of each light bulb.

5F 30.11 - Light The Bulb

Demonstrates: Capacitor storing charge
Description: Charge a capacitor with DC and discharge through a light bulb.

5F 30.30 - Big Circuit Board

Demonstrates: Combinations of R, C and L circuits.
Description: By using the plug-ins and wires several different types of circuits can be created with the "physicist's Lego set." About ten different experiments can be done with the big board.

5F 30.35 - RC Circuit

Demonstrates: Current and voltage in RC circuits
Description: A Tektronix 2445 oscilloscope is used to display charge and discharge times of a capacitor along with the voltage across the resistor. Clearly demonstrates voltage drops across capacitors and resistors

5F 30.40 - Battery & Bulb

Demonstrates: Series and parallel circuits.
Description: A simple set up of two batteries in a holder with two alligator clip leads and bulbs.
