Electricity & Electrical Circuits, Physics
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.

Water Turbine with Dynamo Model
Catalogue No: 1050280
To show the conversion of mechanical energy into electrical energy by making the water turbine to drive a dynamo for producing electricity. The plastic impeller housed in a plastic casing with a clear transparent front that allows viewing of its functioning. The inlet tube provided at the top and outlet tube on the side. Both tubes riffled for tubing connectors. A dynamo mounted along the impeller shaft glows the LED indicating the conversion of mechanical energy to electrical energy.

Wave Machine, Powell’s
Catalogue No: 1120060
For demonstrating the movement of progressive transverse waves. Comprises a number of circular discs mounted equidistant from each others on a horizontal shaft in gradually varying degrees of eccentricity, with each disc having a vertical rod of same length supported on top and sliding up and down into a pair of guides. Complete assembly mounted on a metal base.

Wave Motion Demonstrator
Catalogue No: 1120108
An outstanding version of the classic wave machine. This device consists of a series of pendulums independently suspended on a common base and coupled together by long-light springs. Two modules are included, each with 43 pendulums, a damping unit with a paddle and water bath and a motor-powered eccentric driver for controlled excitation of waves. Coupling hardware is supplied so that the demonstrator can be used with either a single module or with both modules coupled to make a longer machine. The ends of the pendulums are colored bright yellow, while the rest of the machine is black, so the wave patterns are prominent and clearly visible. Basic phenomena in transverse wave propagation can be clearly shown. Using the damping module, running waves can be enerated to illustrate the concepts of wavelength and frequency. Standing wave patterns, wave reflection and superposition can be shown when the damping module is removed. A mechanical brake is also included so that all of the pendulums can be stopped instantaneously, freezing the
wave pattern in place for more detailed discussion. Waves can also be excited by hand.
