Tesla Coil
Catalogue No: 1090685
Its spectacular performance makes it suitable for performing host of activities and demonstration of the undertaking concept including the unusual properties of high frequency electrical phenomena. Light emitting diode glow brightly when held near the coil, a 60W light bulb will light up, harmless spark showers and gigantic sparks can be produced by using two metallic circular discs. Compact version of the classic Tesla design generates high frequency, high voltage. An adjustable spark gap controls both frequency and generates output up to a maximum of over 50kV. We can understand many important topics such as transformer, electromagnetism, resonating electrical circuits, electric inductance, capacitance and electrical power transmission. Supplied with a discharge electrode.

Water Circuit Board
Catalogue No: 1091240
To demonstrate the principle of flow of electricity by analogy. Comprises an analogous circuit made of transparent plastic tubing connected to a low voltage electric pump operating on 6-12V DC for circulating water through the circuit, mounted on a large sheet metal board through spring clips. The circuit has two glass tubes of different bores, connected in parallel across the circuit and represents resistances. Across the resistances is connected a detachable manometer to show the pressure drop across the tubes indicating potential difference. Following the resistances, the tube discharges into a funnel for recirculation through the circuit. 4mm sockets provided for power input to the pump. Rate of flow of water through the circuit represents current through the circuit and can be controlled by varying the input to the electric pump. Hoffman’s Clips provided for disconnecting either of the two resistances or manometer, when needed.

Wheatstone Bridge, Four Gaps
Catalogue No: 1091100/1
For determination of unknown resistances or comparison of resistances. This substantial FOUR-GAP bridge has heavily plated brass strips mounted on a base. Terminals with 4mm sockets are provided to reduce unwanted resistance to a minimum and the gaps are closed by removable brass strips, which are held in position by the terminals. The 24SWG bare constantan wire is stretched on top of meter scale along its length graduated in millimeter and figured at every centimeter. The ends of the wire are securely clamped to the terminating strips to reduce end errors to the negligible level. Wire easily replaceable if damaged or broken. Supplied with jockey.
