Why cell combination needed? A cell is an electrical element which produces current and a battery is a set of some cells with series or parallel connection. A cell is an active element. To increase the rate of current and voltage supply, cells are connected as manner in series or parallel or mix combination. Internal resistance of those cells is important factor while making … [Read more...] about Combination of Cells
Famous Scientist Kepler stated three laws of planetary motion those laws are known by Kepler’s Law of Planetary Motion. Before Kepler many scientist stated different formulas. One by many scientist explained planetary motion theory but all were not correct. It took time to get the right theory of planetary motion although their hard work took us in the perfect conception. First … [Read more...] about Kepler’s Law of Planetary Motion
Electromotive Force is the force on electrical source its an electrical energy which passes through a complete circuit the short form electromotive force is emf. The difference between electromotive force and potential difference or voltage is electromotive is the cause and potential different is the effect. Electromotive force is the source which cause current and potential … [Read more...] about What is electromotive force?
Carnot Cycle was proposed by the Famous French scientist Sadi Carnot planned an engine having no defect or loss. Actually it is not possible no one could make and will not invent that type of engine has no loss because we know from second law of thermodynamics there a loss must converting energy of form to another. Carnot cycle has four steps evolving isothermal and … [Read more...] about Carnot Cycle
Wilhelm Röntgen discovered X-ray production. He was doing research with the discharge tube he observed that fluorescence was produced when cathode rays were incident on barium platino-cyanide sheet placed on the side of the tube. He observed fluorescence on the sheet covering the discharge tube with a thick red paper. Then by placing a thick metallic plate between the sheet and … [Read more...] about X-Ray Production Theory
