Section 3 - Experimental Data Circuit 1. V s = 3V pp ; f = 1300Hz Measured Voltages: V s = 3.02V pp , V 2 = 1.87V pp V 1 (calculated) = 1.22V pp
Circuit 2. V s = 3V pp ; f = 1300Hz Measured Voltages: At V s = 0, V 1 = 681.25 mV amd V 2 = -718.75mV

Section 3 - Questions and discussion 1) Did KVL apply to the resistive circuit? Show explicitly that it did or did not apply. KVL did apply to the resistive circuit: V s - V 1 - V 2 = 0 3.02V pp - 1.87V pp - 1.22V pp = -0.07 V This is close to zero, and the oscilloscope appears to have some issues running peak-to-peak calculations on the math function, which may account for the rest of the difference. 2) From your observation in part e, did KVL apply to RC circuit? KVL also applied to the RC circuit: V s - V 1 - V 2 = 0 0V pp - 0.681V pp + 0.718V pp = 0.037 V Likewise, this is close enough to zero, and the extra errors can be explained through machine and calculation errors. 3) What would have happened to the scope display if the two probe grounds were connected to points with different potentials in the circuit? If the probe grounds were connected to locations of different potential, then they may measure the voltage through a different path or across another segment of the circuit that wouldn’t give the voltage across the intended circuit component. Conclusions After doing this experiment the conclusion can be drawn that an oscilloscope can make measurements with reasonably high precision. Results were off by such a small amount that it can be seen as negligible under the circumstances. The objective to become more familiar with an oscilloscope and its features was achieved. The results of the measurements did agree with the theoretical predictions made. This lab was also useful to become more familiar with the function generator, and with the effects or RC circuits.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
