resistor

Resistive resistor is a non active electrical component to generate resistance in the electrical current flow. In most electrical networks and circuits they are very much present. The resistance obtained is measured in Ohms. An ohm is basically the resistance which happens when a direct current of one ohm passes through a resistor having a one volt drop across the terminals of the resistor. A two Ohm or greater resistor will reduce the currents.

There are two types of resistors that are available in the market, which are surface mount and plate mount. In the surface mount type, the metal traces of the resistor are soldered to the surface of the circuit board through a soldering guide. This type resistors are available in different sizes and resistivity values as per the requirement of the circuit.

 

Plate resistance is used in small electrical circuits. In this case, the resistivity value is directly related with the weight of the circuit. It is available in low, medium and high limit applications. There are several advantages of using this type of resistor in comparison with resistors in the other categories. The plate resistance is connected to the external voltage source.

 

The advantage of using this electrical component is that the device can get power from the source at any time without interrupting the working. Also the voltage across the resistor is fixed and remains same. This makes it easy for controlling the working load in the circuit. One should always select the resistor based on its resistance value. Generally the lower the resistivity, the larger is the current carried by the resistor.

 

Some important characteristics of resistors are length, maximum voltage, resistance to electrical field changes, and Ohm’s law. Resistance is measured in Ohms. The resistance decreases as the current increases. Therefore, one should always choose a resistor whose value is proportional to the voltage across it. Also one should make sure that the resistor does not become hot while it is in use.

 

To maintain the resistance value tolerance, it is better to use a multi-conductor one. This means that there are more than one conductor in the resistor which allows cooling. However, this is not applicable in all the situations. So one should first check whether the electrical current produced exceeds the limits set and then one should opt for a high-resistance resistor which provides adequate protection against fluctuations in electrical current.

kondensator

Kondensator, the scientific name for which is “Kondren’s Cricket Bat”, is a unique type of microscopes’. It is a device which has been named after Kondren who invented it more than 150 years ago. The Kondensator is basically an arrangement of plastic tubing having a circumference as well as an outer diameter much larger than its base and it is attached to a glass sphere which has a focal length equal to or greater than its diameter. In general, kondensator is attached on top of a microscope stage with the objective of using the excitation light from the primary coil of the microscope to illuminate a sample.

As suggested by its name, Kondensator is particularly useful for high-quality specimen preparation and when properly used should stand apart from the typical optical media such as eyepieces, objectives, and filters. To examine a kondensator sample under a microscope, place the sample in the middle of the optical path of the microscope, aim the pointer at the middle of the sample, and focus the lens so as to illuminate only the middle area of the specimen. In order to see a properly resolved image of the specimen under scrutiny, use an eyepiece with magnification ranging from 200x to 400x. A second method of inspecting samples using kondensator involves using a microscope stage with multiple eyepieces which are parallel to each other. The specimen should be placed in the center of this arrangement.

 

Like other specialized microscopes, the unique features of the Kondensator make it suitable for various kinds of experiment. Kondensator can be used in the field of biotechnology, anatomy, and physiology, as well as in many scientific disciplines. The specimen can be mounted on a microscope slide or held in the hand, making it easy to handle and transport. Kondensators can even be mounted onto an ordinary microscope stand, making them easily accessible for students and researchers.

 

An important characteristic of the Kondensator that sets it apart from other optical media is that its image resolution is excellent. Images can be viewed at different f angles, providing the opportunity to perform multiple functions in combination with different specimen specimens. For example, when using a glass microscope for biomedicine, a different specimen can be used at different distances, enabling the researcher to carefully examine cells in different light conditions. The variable kapazit, or hand-held kondensator, also allows users to perform functions such as tissue preservation and immunology testing while simply holding the sample in one hand, which is simpler than when several tools are needed for the same activity.

 

Other versions of the Kondensator include the Strombopad, which is used to recover hard surface stains in water or dry media; the Mephisto, which features the ability to prepare microscope slides by inserting a slide into the device; and the Verichten, which can be used in conjunction with a variety of digitizers. The most innovative version, the Durch Den Kondensator Beispielsweise, is made of translucent acrylic and is intended for use in the field. A flexible neck allows it to be carried around without any restrictions and can be slid into place along with other instruments.

 

Because it enables its users to do more than just look at cells through one or more lenses, many microscopes make use of a Kondensator in order to provide images that are clearer and higher resolution than possible with regular eyepieces. Regular eyeglasses would not be able to resolve images of tissue structure at micrometer levels, as well as the fainter nuances of facial features. This is why regular computers used in research have incorporated methods for reading cell structures from a stromatogram, using a Kondensator as the detector. In addition, regular microscopes make use of Strombopad, which can also recover tissue samples and can help in the detection of disease states such as cancer, when stromatogram results show unusual staining patterns.

Electric diode

Electric diode, The Electric Diode is used for the purpose of changing the current to direct current. It is capable of switching currents in the desired direction. The Electric Diode enables the transfer of energy in a single direction with much greater ease than the others. It is usually represented by a square with a vertical line across the center vertex. It is employed to shield electric circuits from harmful alternating magnetic field by restricting the current to a direct current. This Electric Diode consists of two layers of semiconductors such as gallium arsenide and tourmaline.

The diode produces current in the form of ions, which is highly dangerous. The electric field near the surface of the diode passes through the middle layer of semiconductor. This causes the current to be produced when the electrons near the surface of the semiconductor move in a specific direction. The diode has a control over the movement of electrons, which makes it an efficient source of energy. However, because of the danger it causes, the electric diode should not be placed near any flammable substance.

 

The diode has a diode potential which is proportional to the current. When current passes through the diode it gives off ions which are attracted to the center of the diode. As the current passing through the diode increases, the number of ions produced increases as well. If the current through the diode were to increase to a level where it would create a vapor, the current would be turned off abruptly causing a fire.

 

There are several different applications of the electric diode. In one application it is semiconductor detectors. By adjusting the electric diode current, scientists can tune the detector so that it can detect low levels of magnetic fields. Another application is used for switching. In this application the electric diode can be adjusted so that when the current is turned on, it switches off and vice versa.

 

The diode works best in pairs or in certain groups of two or more. When the current is turned on, the semiconductor is excited and will produce an electric field that will push the electrons from the surrounding area. When the current is turned off, the semiconductor will stop producing the field and the electrons will become neutral.

 

Since the electric diode produces a pulse type of signal, it is often used as a control circuit for microchip applications. For example, some people use the electric diode to control the brightness of a computer screen. This is done by turning on the bright light when the computer is started up. Then when the screen is dark, the bright light will be turned off.
