This course introduces the students to basic of electric circuits through a series of experiments. This includes the working principles of resistors, capacitors and inductors. Students learn different experimental techniques to determine the values of combination of different circuits. The course introduces students to the basic components of electronics: diodes, transistors, and operational amplifiers. It covers the basic operation and some common applications. This laboratory course will help the students in getting familiarized with basic electrical measurement techniques, enhancing ability to apply electrical theory to practical problems, practice in recording and reporting technical information, familiarization with electrical safety requirement and also verification of some basic electric circuit theorems.
