Why learn Basic Electronics?
Electronics has a major role to play in virtually every industry. It increases productivity in sectors like oil, energy, and agriculture. Steel, petroleum, chemical industries depend on electronics for daily processes and functions. Electronics constitutes the largest branch of engineering. In 2002, electronics professionals had around 292,000 jobs out of which most were employed in professional, scientific, and technical services firms as well as government organizations. Some were employed by manufacturers of computer and electronic equipment & machinery, and the remainders were offered placements in firms that dealt in wholesale trade, communications, and utilities.
