A.K. Sawhney's Comprehensive Guide to Electrical and Electronic Measurements and Instrumentation: PDF Free Download



Introduction




Instrumentation and measurement are two essential aspects of electrical and electronic engineering. Instrumentation refers to the devices and systems that are used to measure, monitor, control, and record physical quantities such as voltage, current, resistance, power, energy, frequency, phase, temperature, pressure, flow, etc. Measurement refers to the process of obtaining accurate and reliable data about these quantities using appropriate instruments and methods.

Instrumentation and measurement are important for various reasons. They help to design, test, operate, maintain, and troubleshoot electrical and electronic circuits and systems. They ensure the safety, efficiency, quality, and performance of these systems. They also enable the development of new technologies and applications in various fields such as communication, automation, biomedical, aerospace, etc.


A.K. Sawhney is a renowned author and professor of electrical engineering who has written several books on instrumentation and measurement. His most popular book is "A Course in Electrical and Electronic Measurements and Instrumentation", which was first published in 1973 and has been revised and updated several times since then. The book is a comprehensive course book for engineering students who want to learn the fundamentals and advanced concepts of instrumentation and measurement. It is also a useful reference book for practicing engineers who want to refresh their knowledge and skills in this field.
