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.
* Operates on 220V AC, 50/60Hz. Also available optionally.

Thermal Conductivity Apparatus, Star Shaped
Catalogue No: 1060360
To differences in the thermal conductivity of five different metals: brass, copper, Aluminum, mild steel and stainless steel. These 5 metal rods arranged radially, uniformly spaced on each side of hexagonal brass hub and have a small recess at the outer end for holding paraffin wax. On heating the central hub, the wax contained in the cavities of different metals melts at different times, implying their different thermal conductivities. Fitted with insulated handle.

Thermal Conductivity Bars
Catalogue No: 1060390
Ideal for comparison of thermal conductivity of different metals quickly and conveniently. Features liquid crystal indicators mounted in robust holders. Four identical metal bars of same shape and size, each of different metal: copper, aluminumm, brass and steel held firmly in a rigid moulded plastic carrier with a hole for convenient suspension. Thermal conductivity value of each bar is clearly marked. The sensitive liquid crystal temperature indicators working in low temperature range are attached to each of the four metal bars and are marked at 1cm interval to facilitate charting the movement of temperature gradient. The rate of heat flow is indicated by timing the colour change across these markers. The demonstration requires only a container of hot water, thus doing away with open flames, hotplates, or messy melting wax method of comparison with result in a very short time. Timing the heat pulses enables estimation of the relative conductivities.

Thermistor Investigation
Catalogue No: 1100510
A NTC (Negative Temperature Coefficient) based thermistor with a nominal resistance of 4.7K Ohm housed in a glass tube with electrical connection made by means of 4mm flexible banana plug leads. On heating the glass tube, the resistance of the thermistor will dramatically decrease and can be measured on plugging the end leads in a digital/analogue multimeter and selecting the appropriate range of resistance.
