Electrostatics holds 21 items for static electricity experiments in school and college physics labs. They include two high-voltage generators, three electroscopes, the conductors and nets for showing where charge sits, a condenser, a Leyden jar and a large capacitor, charging and transfer tools, and a class kit. Specifications are as given in each listing.

Generators

Generator	What the listing specifies
Van De Graff Generator (Motor Driven)	Motor-driven belt generator on 220-240 V, 50/60 Hz mains, fused, with an on/off switch; one-piece near-spherical dome 20 cm in diameter on a Perspex column; up to 200 kV and a spark of up to 70 mm under favourable conditions; 550 mm high; 4 mm earthing socket, 4 mm insert on the dome, and a discharge sphere on a long insulated handle; accessory kit included
Wimshurst Machine	Traditional influence machine giving sparks of up to 75 mm; 450 x 175 x 500 mm

The Van de Graaff generator is listed for experiments that need a continuous source of high voltage, and runs from the mains. The Wimshurst machine is the traditional influence machine, and gives the longer spark of the two at up to 75 mm.

Detecting charge

Electroscope	What the listing specifies
Gold Leaf Electroscope	Single gold leaf in a metal case with a 4 mm earthing terminal, clear front and ground glass rear windows, on a Bakelite base; two interchangeable electrodes, a 50 mm disc and a metal hook; 112 x 63 x 143 mm high
Gold Leaf Electroscope, Flask Type	Hard glass conical flask closed by a holed rubber stopper, with a metal rod carrying a top disc and a pair of foil leaves inside
Electroscope Pith Ball	Two pith balls hung on unspun silk from a chrome-plated brass pillar on a base

Where charge sits on a conductor

Faraday Ice Pails: four nesting aluminium cylinders on insulating feet, 150 x 120, 120 x 110, 90 x 90 and 75 x 75 mm, to show that charge resides on the outer surface of a hollow conductor.
Butterfly Net: a fabric net with a cord on an insulating pillar, to show that charge resides on the outside of a conductor.
Sphere Conductor, Cylindrical Conductor and Conical Cylinder: hollow brass conductors on insulated pillars, for comparing charge distribution and charge-holding capacity by shape.

Storing charge

Item	What the listing specifies
Aepinus Condenser	Two 100 mm metal discs on insulated handles and pillars, with a glass dielectric plate that can be swapped for other materials; 4 mm sockets; for the relationship between charge, voltage and capacitance
Leyden Jar	Two aluminium jars, one with an electrode, and one plastic jar; 100 mm high, 75 mm in diameter
Large Electrolytic Capacitor	Capacitor in clips on a box with 4 mm sockets, for energy-storage experiments showing that stored energy is proportional to V squared

Charging and transfer tools

Electrophorus: an insulating Bakelite disc with a brass disc on an insulating handle and a small sphere for earthing it, for producing charge in small quantities.
Proof Plane: a metal disc on an insulating handle about 150 mm long, for carrying charge from one object to another.
Discharger: electroplated brass spheres on curved arms joined on an insulating handle, for discharging objects or transferring charge.
Electrical Whirl: a 60 mm six-pointed star wheel with points curved one way, which turns on its pivot under discharge from the points; 4 mm socket on the base.
Electric Fields Apparatus: a clear plastic dish 90 mm across with two height-adjustable electrode holders and six electrodes, including rings of 35 and 70 mm, for showing electric field patterns directly or on an overhead projector.
Friction Rods Set: six rods about 30 cm long and 12 mm in diameter, in ebonite, glass, polythene and Perspex, plus two compound rods of glass and ebonite and of glass and brass. The Friction Cloths Set adds silk, wool, rubber silk and raised flannel, each about 30 x 30 cm.

The class kit

The Electrostatics Kit gathers the basics in one box: an electroscope, a polishing cloth, four metallised polystyrene spheres with nylon thread and a wire hook, an electrophorus plate and a proof plane on insulating handles, a stirrup, cellulose acetate and polythene strips, two polythene tiles and two aluminium cans.

Questions buyers ask

How high a voltage does the Van de Graaff generator reach?
Up to 200 kV with a spark of up to 70 mm, under favourable conditions, according to its listing. It runs on 220-240 V mains.

Which electroscope suits demonstrations to a class?
The Gold Leaf Electroscope, with its 4 mm earthing terminal and interchangeable disc and hook electrodes. The flask type and the pith ball electroscope are simpler alternatives.

What sizes are the Faraday ice pails?
Four nesting cylinders: 150 x 120, 120 x 110, 90 x 90 and 75 x 75 mm (diameter x height), each on insulating feet.

Is there a kit for student groups?
The Electrostatics Kit brings an electroscope, charging strips and tiles, spheres, an electrophorus plate and a proof plane together in one set.
