ELECTRICAL SUBSTATION A substation is a part of an electrical generation‚transmission and distribution system. Substations transform voltage from high to low‚ or the reverse‚ or perform any of several other important functions. Electric power may flow through several substations between generating plant and consumer‚ and its voltage may change in several steps. Substations may be owned and operated by a transmission or generation electrical utility‚ or may be owned by a large industrial or commercial

Study of passive filter characterization for PCB application Chapter 1: Introduction Project Description Passive filters are relatively simple electronic part that consists with resistors‚ capacitors‚ and inductors. The function of the passive filter is to allow a certain range of frequencies to pass‚ can be used to separate signals‚ passing those of interest‚ and also can reject noise and attenuating the unwanted frequencies. In this project‚ there are three type of passive filters that

Investigatory Projects in Physics | Repulsorlifts as a Method of Stable Magnetic Levitation | Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength‚ size‚ and temperature increase‚ which were done in the preliminary testing. The prototype road and car were

Golf has gone from a game played by farmers in the fields to a sport played by millions of people world wide. As the years have passed players have gotten better‚ clubs are hitting straighter and balls are flying higher and further than ever before. This has little to do with the golfswing‚ which hasnt changed

ascertaining the inverse of conductance. The reasons for this will be provided within the Discussion/ Conclusion section. The resistance of an object is determined by the nature of the substance of which it is composed and this is known as the resistivity which are the dimensions of the object and the temperature. Resistance‚ however‚ is expressed in terms of the Ohm resistance per cubic centimeter at 20 oC (293 K). In its simplicity‚ before resistance is calculated‚ conductance is first obtained
