WORCESTER CIRCUIT BOARD KIT

WORCESTER CIRCUIT BOARD KIT

The kit consists of baseboard, terminals, set of metal connection pillars and a number of clip-on connection strips and accessories units, enabling a variety of circuits to be constructed quickly. Phosphor bronze connection strips are so designed that when flexed a little, they are easily slipped over the pegs on baseboard, where there natural spring holds them in position and ensures good electrical contact. The kit includes following components. Flash Lamp Bulbs 18 nos, Plain Connectors 12 nos, Connectors with Lamp Holders 9 nos, Connector with Rheostat 1 nos, Rectifier 1 nos, Resistor 1 nos, Flexible Leads with 4mm plugs and crocodile clips 2 nos, Flexible Leads with Crocodile Clips 2 nos, Crocodile Clips 2 nos, Mounted Bell Pushes 2 nos, Soft Iron Nails 50mm 2 nos, 1 Length of Bare Copper Wire 20SWG, 1 Length of Bare Eureka Wire, 34SWG, 1 Length of Plastic Covered flexible wire, Circular Hardboard Disc, Drilled 1 nos, Pencil Leads 4 nos, Copper Foil 1 pc., Steel Wool Supplied without cells 1 pc. The Worcester Circuit Board Kit has been so comprehensively designed that no catalog specification or illustration can properly indicate the complete scope of the kit. Listed below are some of the topics that can be studied on an inspanidual basis. (1)Understanding basic electrical circuit elements and their applications (2) Making simple electrical circuits. (3) Simple series and parallel circuits. (4) Conversion of electrical energy to light energy and heat energy. (5) Heating Effects of current (6) Magnetic effects of current (7) Current Balance. (8) Effects of a resistor and a rectifier (9) Using simple variable resistor as a potential spanider (10) Testing Fuses (11) Comparison of resistance wires. (12) Conduction in liquids Simple CeIl. (13) Electroplating etc.More experiments and demonstration can be performed with the kit and are left to the ingenuity of teachers and students for further exploration.
X-RAY TUBE, COMPLETE

X-RAY TUBE, COMPLETE

Combined unit with built in X-Ray screen holder, induction coil working on 12V DC, 6A, with X-Ray tube and fluorescent Screen.
X-RAY TUBE, ROENTGEN

X-RAY TUBE, ROENTGEN

For use with electronic machine or induction coil, with vacuum regulating device. Comprises a glass sphere with a concave disc electrode generating cathode rays and focusing it on a tungsten target, placed at an angle of 450 at the inner end of arm exactly opposite. These tubes produced soft X-Rays and care must be taken from over exposure. Available in tube sizes (diameter)
YOUNG'S MODULUS APPARATUS, ECONOMICAL

YOUNG'S MODULUS APPARATUS, ECONOMICAL

Useful for studying the relationship between load applied to a wire and the resulting extension i.e. Young's modulus of elasticity of the wire material. Can also be used for comparing elastic moduli of two different wires. Two thick sheet metal strips with clamping screws at the top for wires and metal hooks for the loading masses. are mounted in a rectangular plate. ,,- parallel to each other. The plate has a scale 0 - 40 x 1 mm along with a movable Vernier of LC O. 1 mm. attached to one of the metal strips. Also included is a ceiling clamp with a pair of wooden screws for suspending wires from the top and can be attached to a convenient overhead beam or door frame etc. supplied complete with a tension weight and a set of two wires - 1 each of brass and steel
YOUNG'S MODULUS APPARATUS, SEARLE'S TYPE

YOUNG'S MODULUS APPARATUS, SEARLE'S TYPE

A specially designed apparatus capable of greater degree of sensitivity and accuracy. Two cast metal rectangular frames hinged together parallel to each other to allow only vertical relative motion, with a spirit level fixed on a cross-bar pivoted across the frames for noting the reference point. One frame has vertical scale 10-0-1 Omm wit.h a micrometer head along it reading to 0.01 mm for adjusting the spirit level. Each frame has a self?centering chuck at its top for holding wires and load hooks at the bottom. Also included are ceiling bracket carrying a pair of chucks. a counterpoise weight and a set of two wires, one each of brass and steel. The relative displacement between the two frames can be known from the micrometer reading after adjusting the bubble of Spirit Level.
