Experiment #11 AC Circuits April 10, 2019 Jenna Winsett Partners: Aaron King Jeremiah Grant PH234.02
Apparatus Sketch: Procedure: the objective of this lab is to measure and be able to calculate resistance, impedance, and phase angles. This is all regarding AC circuits and being able to use the oscilloscope to help with the calculations Part 1: 1. Set the resistance to 500 Ohms, capacitor to 0.5 µF, and frequency to 1000 Hz. Channel 1 on the oscilloscope will be your x-value and channel 2 will be your y-value. 2. Set the oscilloscope to x-y mode and measure the phase angle by = sin ɸ ɸ -1 (B/A). the values for A and B can be found on the oscilloscope screen. 3. To find the theoretical phase angle, use = tan ɸ -1 [(2Πfc) -1 /R]. once both the theoretical and experimental phase angles are found, calculate the percent error. 4. Measure the current of the circuit as well as the maximum and AC voltages across the resistor, capacitor and RC combo. Calculate the RMS voltage for each using V RMS = V

### 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.
