3.1 AC – peak, peak-to-peak, average, RMS

Understanding AC Measurements
This chapter introduces the foundational concepts of alternating current (AC) measurements, vital for anyone involved in electrical engineering or working with electronic devices. The focus is on understanding various amplitude dimensions of AC signals, such as peak, peak-to-peak, average, and RMS (Root Mean Square) values. These measurements are crucial for accurately analyzing and interpreting AC waveforms, especially when viewed through devices like oscilloscopes. The chapter also delves into how these measurements are used in practical applications, including the calibration of AC voltmeters and the application of Ohm’s law in AC circuits. By grasping these concepts, learners gain a comprehensive understanding of how AC voltages and currents are measured and interpreted, laying a foundation for more advanced studies in electronics and electrical systems.
