Lecture 1: Signals & Measurement, Dr. Wim van Drongelen

[@wvandron]

Stanislav, The currents we talk about here are not at the level of the electric chair, and indeed not harmful in that sense. However, even small currents could affect the properties you are trying to record and that's not what you want for an objective measurement. Therefore, (since without current measurements cannot be made) it's a good idea to minimize currents in a recording device. WvD

Dear Prof., the lab webpage link is not working.

[@wvandron]

@@ashekatmvlg I discontinued the lab website, you can use the other link above

[@wvandron]

The current video refers to the 1st editions of both textbooks. I will now add the reference to the 2nd edition of the textbook that includes all material. This Video is also CH 1 and 2 in the 2nd Edition.

[@ElectricTeaCup]

Hello! Thank you for sharing your fantastic course. One question, is there any open courseware for this course? (exercises, notes, tests, exams, etc)? I was wondering if this course can be done individually

[@wvandron]

@@ElectricTeaCup the only way to follow the course, other than using the KZbin videos, is as a U of Chicago or IIT student, sorry. There are exercises in the 2nd Ed. Of the book and more material plus selected answers on the book’s website.

As someone who doesn't understand electronics.. Why is current annoying? It's the source of information for our detectors, so how does it harm exactly?

See my comment above

Hello, because in this exemple we are trying to measure the voltage V not the current, a significant current will dissipate in the resistor and will cause a decrease in the voltage by Ro*I ( V=Ro*I+V') . If we want to measure the current we will use a different setup.
