A Capacitor or a Condenser is a device for storing charge. A combination of two conductor plates of area A, put closed to each other separated by a small distance d is called a capacitor. Add caption These plates could be of any shape -a sphere ,cylinder or flat plate. The geometry of the capacitor plates determines the capacitance for a given plate conductor area. Usually the space between the plates is filled with a dielectric medium of relative permittivity ℰ. The earliest capacitor was invented accidentally by Van MUSSCHENBROEK of Leden in about 1746 and became known as a Leden Jar. Technically any conducting material has some resistance,capacitance and inductance . If we put some charge on a piece of aluminium foil it will retain it until someone touches it or somehow it makes contact with a nearby substance,however its charge storing capacity is very limited since excessive charge density will lead to Corona Discharge. A marvelous example of such capacitor is Van De Graff Ge...
Image file formats are standardized means to store Digital image data which can be either in Raster or Vector format .Once rasterized they become a gid of pixels There are several image file formats that can store images either with lossy or lossless compression methods. Each having their advantages and disadvantages .Though no. of Image storing file formats is not very limited. Some native applications use their own file formats for storing image data such as photoshop (.psd),corel draw(.CDR) that have been created to provide some additional features over conventional file formats. Recognizing file format File formats predicts much about file Data. It helps us in listing/sorting of the files which can be opened with a particular kind of application. File format can be simply found at the last of a file name begins with a (.) dot. While some applications may hide this information from the file name to prevent accidental renaming of the file extension/ format, which might ...
