Quelle est la valeur d'amplitude la plus facile à mesurer lorsqu'on analyse une onde sinusoïdale pure à l'oscilloscope?
- ALa tension de crête
- BLa tension efficace ("RMS")
- CLa tension moyenne
- DLa tension de crête à crête
Correct answer: D — La tension de crête à crête. Question tirée de la banque officielle d'ISDE.
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.
