What is the easiest amplitude dimension to measure by viewing a pure sine wave on an oscilloscope?
- A RMS voltage
- B Average voltage
- C Peak-to-peak voltage
- D Peak voltage
Correct answer: C — Peak-to-peak voltage. From the official ISED question bank, verified word for word.
Why
Peak-to-peak voltage is the easiest to measure on an oscilloscope because you simply read the vertical distance from the very top of the wave to the very bottom, which corresponds directly to the screen markings. The full explanation — and one for every question — is in Pro.
