Electrical Measurement: Fundamentals and Instruments

Electrical measurement is the foundation of electrical engineering, allowing you to diagnose circuits, verify designs, and ensure system safety. Without accurate measurement, complex electrical work is impossible. By the end of this course, you will possess a solid theoretical and practical understanding of how standard electrical quantities are measured, including the ability to select the correct instrument and minimize measurement errors. What you'll learn: * Understand the core principles governing analog instruments, including PMMC, moving iron, and electrodynamometer mechanisms. * Master the operation and application of standard meters for measuring voltage, current, resistance, and electrical power. * Analyze sources of error and uncertainty in measurement, including techniques for instrument calibration and standardization. * Apply bridge circuits (such as Wheatstone and Kelvin) for precise determination of resistance and impedance. * Configure basic digital measurement systems and understand the principles of analog-to-digital conversion (ADC) and sampling. * Practice interpreting instrument specifications and ensuring measurements comply with established standards. The course begins with foundational definitions and units, progresses through the construction and theory of common analog and digital instruments, and concludes with essential techniques for error analysis and precision measurement. This course is designed for absolute beginners, students, and technicians starting in electrical engineering. No prior knowledge of measurement theory is required.
