ELECTRIC FIELD APPARTUS. Used to give visual demonstration of electric fields. This consists of a flat, transparent plate or grid with a set of conductive electrodes embedded in it, and a power supply that generates an electric field between the electrodes. A transparent plastic base 150mm square, support a dish 100mm diameter and two 4mm socket terminals, mounted on insulating pillars. Complete with two wire point electrodes to provide a parallel field. Two point electrodes are mounted through side pillars When connected to power supply electric field lines are clearly visible around and between the electrodes.

MS-420 PVG FARADAY ICE PAILS

For demonstration of Gauss’s Law for distribution of charge and the dependence of field strength near a conductor on its radius of curvature. Comprises a hollow cone 120 x 50 mm., a cylinder 120 x 50 diameter and a sphere of 50 mm. diameter. Narrow end of hollow cone is rounded to make good contact with a proof plane and to reduce charge leakage. Each mounted on insulated pillars with bakelite base

MS-423 PVG GOLD LEAF ELECTROSCOPE FLASK TYPE

GOLD LEAF ELECTROSCOPE A scientific instrument used to assess the presence of electrical charges on a body is known as an Electroscope. A gold-leaf electroscope is electroscope that consists of gold leaves and is used for detecting the electrical charge of the body. Strongly constructed ,powder coated, sheet metal walls of the electroscope and are mounted on a plastic base. Front glass window slides up to allow insertion of ionizing material in chamber. Transparent scale is attached inside chamber to measure the deflection of the gold leaf. When a charged object touches the electroscope's brass disc, the electric charge gets transferred to the gold leaves through the rod. This results in the gold leaves moving away from each other as like charges repel each other. The movement of the leaves shows the presence of charges in a body. The gold leaves return to their normal position after some time. This happens because they lose their charge after a while. This process is called electrical discharge. The charges in the gold leaves would also be discharged when someone touches the brass rod with empty hands. In that case, the charges are transported to the earth through the human body.
