Course details

This is a core subject for all undergraduate Electrical Engineering students, and its syllabus is fully aligned with the GATE EE examination.You will learn how common electrical measuring instruments work and how they respond to changing signals. This includes basic instruments like ammeters, voltmeters, ohmmeters, wattmeters, and energy meters. The course also covers methods for measuring resistance and impedance, different types of bridges and potentiometers, and the use of instrument transformers.This part focuses on modern electronic measurement systems. You will study differential amplifiers and operational amplifier (op-amp) circuits, analog DC and AC instruments, analog-to-digital and digital-to-analog converters (ADC and DAC), digital measuring instruments, and commonly used lab equipment such as function generators and oscilloscopes.
