		<description><![CDATA[The Electric double layer capacitor has the main use of a Charge Reservoir. That means a large amount of electrical charge in a small footprint.
These charge/discharge quickly unlike the battery, There is no Electrical Energy to Chemical Energy Transformation and back, like in batteries. It may need caution in design and usage as they may [...]]]></description>

		<description><![CDATA[Selecting the parts for your product design, choosing the components intelligently is a part of Product Design Engineering.
Budget, Availability, Size, Alternate Vendors, Product Life and Quantity to be manufactured are some factors that determine the selection of a prudent and experienced design professional.
To choose the right type of part, an exhuastive knowledge of the behaviour [...]]]></description>

		<description><![CDATA[Potentiometers, Rheostats, Trimpots, Presets are Variable Resistors. These are user interface devices. When a user turns a dial on a Panel it moves a wiper on a resistor film or wire-wound former. The variable resistors are also used to calibrate circuit sections on a board. These are used for either to obtain a precision or [...]]]></description>

		<description><![CDATA[Resistors were first made by winding thin high resistance alloy wires on a former and then encapsulating it. This method is still used for high wattage resistors. One example is a rheostat, the other that still is used is a wire wound potenmtiometer.
Then we have carbon film, which means a very thin carbon film is [...]]]></description>

		<description><![CDATA[Principles of Semiconductor Devices
The purpose of this text is to explore the internal behavior of semiconductor devices, so that we can understand the relation between the device geometry and material parameters on one hand and the resulting electrical characteristics on the other hand.

Schottky diode current
Metal-Semiconductor contacts
Electrostatic analysis of a p-n diode
Reverse bias breakdown
Optoelectronic devices
Light Emitting [...]]]></description>
