This box changes resistances in a laboratory circuit.

Demonstrate the conversion of mechanical energy into electrical energy by generating a static charge.

Obtain quantitative data for electrostatic experiments

A Highly Sensitive Electroscope

Six aluminum replacement leaves for the Electroscope Assembly without Flask.

A thin aluminum coating produces great sensitivity to electrostatic charges. Styrofoam pith-like balls measure 8 mm in diameter and each has a silk suspension cord.

The Air-Cooled Laboratory Rheostat is the classic lab solution for controlling voltages and currents.

Electrostatic charges are indicated by the deflection of a black plastic straw pivoted on a pin. The polished zinc plate on top is used to demonstrate photoelectric effect and various other electrostatic demonstrations. The metal case measures 14 cm in diameter. The scale is graduated in 10° increments in two quadrants.

Used to Detect Electrostatic Charge

Enough materials for a complete class to perform all of the electrostatics experiments included in this set.

Pith balls are an electrostatic necessity.

Create Dramatic Electrostatic Effects

These robust and engaging kits are designed as a resource for the teaching of introductory electricity.

This complete set of materials makes possible multiple dramatic demonstrations of basic electrostatic principles.

The concept of electric fields can be difficult to visualize, but the Dry Field Mapping Kit makes it easy.

Economical set for studying friction.
