Biots Apparatus for Physics Lab is a spherical conductor on insulating stand with insulated handle, to show that electrostatic charge resides on outer surface.
Comprising two metal discs, with variable separation, supported on insulating pillars & provided with insulating handles on the ends of the adjustment slide rods, 4 mm sockets too are drilled onto the ends of the rods.
A cycle dynamo mounted on a wooden base 200 x 115 x 12 mm & provided with two sets of gears driven by a hand crank for fast or slow rotation. Two 4 mm socket terminals are provided for the dynamo output. Connected in parallel with an MES lamp holder & 2.5 V bulb.
Comprises a shallow glass dish100 x 10 mm & a pair of socket terminals/ electrode holders that clip onto its rim. A compliments of six electrodes is supplied, two point source, two line source & two circular rings of 70 & 35 mm diameter respectively.
Electroscope Simple Flask Type for Physics Lab A 100 ml conical borosilicate glass flask, brass rod with disc & gold leaf attached, supported in cork with polythene insert.
For demonstrating that an electrical charge resides on the external surface of a conductor. Net with cord on insulating pillar with metal tripod base. Overall height 350 mm approx.
Van De Graff Generator Designed for electrostatic experiments and where continuous source of high voltage is required. Fitted on base with smooth running A.C. Motor, operates on 220 volts A.C. 50 Hz. Charge collecting Silicon rubber having excellent. Belt : insulation resistance. Tracking : Belt-tracking easily adjusted.Charge collecting combs : Aluminium mesh, clearly visible.
Wimshurst Machine - The two plates are supported in two rigid uprights and driven by belt in opposite direction. They are heavy, high resistance plastic with sectors of aluminium sheet. Two leyden jars (condensers) made form corning glass and
aluminium foil. The whole is mounted on a wooden base nicely polished.
