Introduction to AC Circuits
Pure Capacitive circuits: When the switch is closed in the circuit above, a high current will start to flow into the capacitor as there is no charge on the plates at t = 0 . The sinusoidal supply voltage, V is increasing in a positive direction at its maximum rate as it crosses the zero reference axis at an instant in time given as 0 o .
Extraction Process of Aluminium from Bauxite Ore
Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes. Bauxite is the general name given to the hydrated oxides of aluminum. It contains varying amounts of

Optimization is a common form of decision making, and is ubiquitous in our society. Its appliions range from solving Sudoku puzzles to arranging seating in a wedding banquet. The same technology can schedule planes and their crews, coordinate the production of steel, and organize the transportation of iron ore from the mines to the ports. Good decisions in manpower and material resources
