Electrical measurements are the calculations, methods, and devices utilized for measuring electrical quantities. Electrical and electronic measurement as a discipline deals with the measurement methodologies and procedures by utilizing electric and electronic technologies. It also focuses on the implementation, testing, characterization, design, and calibration of measurement systems. The measurement of electrical quantities is used for determining a system's electrical parameters. Physical properties like pressure, force, temperature, and flow can be transformed into electrical signals by using transducers to measure and record these properties. In day-to-day industrial practice, less exact measurements are required, whereas high precision measurements are utilized in experiments for determining speed of light, charge of an electron and more. This book is a valuable compilation of topics, ranging from the basic to the most complex advancements in the field of electrical and electronic measurements. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. The book is appropriate for students seeking detailed information in this area as well as for experts.
