Tension Alternative sinusoïdale et Oscilloscope (Collège, 3ème)

#onlinecourse #middle school #electricity #voltage In this video, we'll study sinusoidal alternating voltage, part of the 9th-grade curriculum under the theme "Energy and its Conversions." We'll see how to measure it using an oscilloscope and how to read the characteristics of an alternating voltage on the resulting oscillogram: the maximum voltage Umax the period T And using these values, we'll see how to calculate: the RMS voltage Ueff the frequency f of the periodic signal. I used an online simulator to show you how to use the oscilloscope, rather than filming it live, to make it clearer and easier to follow. You can also access it and try it out. It's really easy to use (thanks to the middle school teachers who created this simulator!). Here's the link: http://www.pccl.fr/physique_chimie_co... Good luck!!
