Oscilloscope Voltage Measurement Concepts

The video tutorial explains how an oscilloscope measures voltage changes over time. It covers the basics of oscilloscope traces, comparing potential differences between power supplies, and analyzing AC and DC waveforms. The tutorial highlights the importance of understanding the amplitude and characteristics of different waveforms using an oscilloscope.

What is the primary function of an oscilloscope?

• To measure the change of voltage as time passes

• To measure the speed of light

• To measure temperature changes over time

• To measure sound waves
