Box of Resistors
Plastic breadboard with 3 LEDs and 3 terminals. Two LEDs are wired oppositely in parallel to the plus and minus terminals.
Breadboard With LEDs
An iron-core solenoid with a rounded handle fits neatly inside a larger air-core solenoid. Each coil has a pair of banana-plug terminals.
Coil Set
A collection of copper objects. Some are sections of thick wire, some are thin sheet strips.
Copper Electrodes
A double-pole knife switch mounted centrally on a weathered rectangular base throws to contacts on either side. The switch has banana plug connectors and the contacts on one side connect to clips for holding wires.
DPDT Switch with Wire Clips
An iron-core solenoid fits neatly inside a larger air-core solenoid. Each coil has a pair of banana-plug terminals.
Induction Coil
A glass jar roughly the size of a water bottle, with the lower half lined inside and out with metal foil. A wooden plug supports a metal ball on top of a brass rod, and a chain dangles inside the jar.
Large Leyden Jar
The multimeter is a rectangular white box about the size of a small cooler. It has a four-digit red LED deisplay two inches tall, four banana sockets, a thermocouple port, and a BNC pH probe connector.
Lecture Multimeter
A glass jar a little larger than a soda can. The lower half is lined inside and out with metal foil. A rubber plug supports a metal ball on top of a rod, and a chain dangles inside the jar.
Small Leyden Jar
A single-pole knife switch mounted centrally on a weathered rectangular base throws to contacts on either side. All three contact points have a banana plug connector.
SPDT Switch
A pair of bent metal strips, one zinc and the other copper. The zinc is J-shaped, while the copper is closer to a U with a tail.
