A transistor, made of a solid piece of semiconductor material, is a semiconductor device used to amplify and switch electronic signals. It has at least three terminals for connection to an external circuit. A voltage or current applied to one pair of transistor's terminals changes the current flowing through another pair of terminals. The transistor amplifies the signal since the controlled...

Metal Detector
2010-10-06 21:55:14

A metal detector is a device that finds metal that may not be visible. The basic metal detector is composed of an oscillator producing an alternating current that passes through the coil producing an alternating magnetic field. If electrically conductive metal is close to the coil then the magnetic field is disrupted and thus the metal detector can sense the hidden metal. The first metal...

Incandescent Light Bulb
2010-09-29 16:52:36

The incandescent light bulb provides a source of electric light through incandescence. The bulb works by passing current through a filament which heats to a temperature that produces light. The glass bulb that contains the filament prevents oxidation of the hot filament. The bulbs are also called electric lamps. Incandescent bulbs come in a various sizes and voltages. They can range from...

A thermostat regulates the temperature of a system and keeps the system's temperature at desired setpoint temperature. The device does this by turning heating and cooling devices on and off and regulating air flow of a heat transfer fluid as needed. This maintains the correct temperature. Thermostats may be used to control heating or cooling a system, or may be a component part of a heater...

Perlite is an amorphous glass mineral of volcanic origin. Typical analysis: 70-75% SiO2, 12-15% Al2O3, Na2O 3-4%, K2O 3-5%, Fe2O3 0,5-2%, MgO 0,2-0,7%, CaO 0,5-1,5% Loss On Ignition 3-5% Properties: When it reaches temperatures of 850"“900 °C, perlite softens (since it is a glass) and water trapped in the structure escapes and this causes the expansion of the material to 7"“15...
