Basic Instrumentation Skills (Generic Elective Theory)
Course Objectives:
This course will enable the students to get exposure with various aspects of instruments and their usage through hands-on mode. The student learns working of various sophisticated and electronic measuring instruments like, C.R.O., VTUM, Conversion of Galvanometer in to Ammeter and Voltmeter, multi-meter, colour codes of resistance, capacitors etc., so that he/she can design their own electronic circuits.
