Introduction to Electrical and Electronic Circuits  by Prof.M.B.Patil sir

Dr. Mahesh B. Patil received B. Tech. from IIT Bombay in 1984, M.S. from the University of Southern California in 1987 and PhD from the University of Illinois at Urbana-Champaign in 1992, all in Electrical Engineering. He was involved in fabrication of HEMT's and Monte Carlo simulation of compound semiconductor devices at the University of Illinois. He spent one year (Dec 1992 to Dec 1993) at the Central Research Laboratory, Hitachi in Tokyo, where he worked on simulation of MOS transistors. From Jan 1994 to June 1999, he was with the Department of Electrical Engineering at IIT Kanpur. Since June 1999, he has been with the Department of Electrical Engineering at IIT Bombay. His current research interests include device simulation and circuit simulation.

  Notes on selected topics:
  "What will happen if the voltage across a capacitor changed suddenly? Will the sky fall down?"
  The answer to such questions (which will not appear in your exam but are important nevertheless) may be found in these notes.
  A good way to use these notes is the following:
  

  1. Read the "Background" section of the chapter.
  2. Try the solved examples. Do not look at the solution.
  3. Check your answer/reasoning with the solution given. Sometimes, you may find that there are altogether different approaches for solving a given problem.
  4. Simulate the circuit in question. It enables you to look at various currents and voltages and will often lead to a better insight.
  5. Try the Exercise Set.
