chemistry is used in many ways in computers also.for example.‚we use many elements like silicon‚zinc‚aluminium‚copper etc.‚. in designing and in developing the hardware of computer. Electronics: Chemistry is important in many electronics fabrication and packaging methods and may one day help extend the trend toward faster and cheaper electronics by \molecular electronics‚" where individual molecules are used as electronic components.

Generator reactances are used for two distinctly different purposes. One use is to calculate the flow of symmetrical short circuit current in coordination studies. A second use for generator reactances are in specifications that limit the sub-transient reactance to 12% or less in order to limit the voltage distortion induced by non-linear loads. For either short circuit or harmonic distortion analyses‚ the stated reactances will need to be converted to a common base to make valid comparisons. Typically

generation computer. Second generation (1959-1965) computer consisted of transistors i.e. vacuum tubes were replaced by transistors. Thus the size of the computer got reduced considerably. Third generation (1966-1973) computer consisted of integrated circuits (IC) i.e. many transistors in single silicon chip. A single IC has many transistors‚ registers and capacitors built on a single thin slice of silicon. With the invention of microprocessor (1971)‚ fourth generation of computer evolution started

Change Plan: Circuit City Kara Burke Keller Graduate School of Management One major change that took place in the Circuit City organization was its bankruptcy and liquidation of its assets. I was unable to find any communications that occurred within the organization‚ much less externally to stakeholders. What I was able to find were many news communication pieces from third parties. The communications highlighted all the stages of this change‚ from the announcement of bankruptcy filing to

DC Circuits - Analysis and Design Alexander Glover‚ z3422512 Abstract DC circuit analysis and design‚ play a massive role in electrical engineering and without the correct application of theory and practise in unison‚ nothing can be achieved in a true engineering sense. Engineering requires theory to develop and test constraints while also requiring practical application of theory in order to determine tolerance and practical results for industry purposes. The ability to analysis a circuit gives

These include the desktop that is in many homes to the cell phones in your pocket. Even things like your car‚ dishwasher‚ dvd player‚ and even TVs include some form of computers. All this would not be possible without the invention of the integrated circuit or IC. This led to the creation of the Microprocessor or CPU (central processing unit) which acts as the brain of the computer. To better help illustrate the function and need for a CPU you must go back to the first all electric computers. Now computers

Q-Meter The Q meter is an instrument used to measure electrical properties of coils and capacitors. Mostly used in testing the radio frequency circuits. A Q-meter basically measures the Q (Quality Factor) of the circuit. It is also used to test the inductors‚ capacitors for their high frequency inductance‚ Q ‚ capacitance as well as ∑‚ tg δ value.
