Question:

[Qg-Lab/Demonstratiom * *] We discussed above that resistance is a geometrical property (length and area) but also resistivity but also a property of the material (resistivity). This is the case for an \"ideal\" resistor since as we also discussed, current increases temperature which, further increases resistivity (i.e. a non-Ohmic behavior like the bulb). However, there is another parameter that can weigh in and make the resistance behave differently; frequency. Start with a low frequency square-wave connected to any resistor on your PASCO board at 10 Vp. We gradually increase the FG to its maximum frequency possible (150 kHz) and at the same time observe the screen of our scope. As we go to higher and higher 13 PH 115-LABORATORY MANUAL, OHM'S LAW IN AC/DC, UAH PHYSICS 2020-2021 frequencies the pure square-wave that we started with, is gradually replaced with a \"shark-fin\" shape. See demonstration here. Q\") Provide a tentative physical explanation for what happens to the voltage time-series and how this behaves as the frequency goes higher. Remember it since we are going to see it again in lab 4 Ge. the resistor behaves like a capacitor). Q33) If you had to make measurements across a wide range of frequencies which instrument would you likely rely on? The DC or the scope? Watch this experiment here and discuss your results
