Question 4. At approximately which frequency would be the half-power point? The half power occurs when . Matching this with the equation for frequency, , we can find the frequency: Conclusion Overall, this lab helped immensely to learn the sinusoidal details of alternating current circuits. Our data confirmed our math, for the most part, with error cropping up only when the lack of precise measuring ability did at higher frequencies. However, when this did happen, the error seen was large. Much like in an experiment a very long time ago, when we received an abnormally high error percentage, this is due to the small magnitude of the values, where even a slight change in the measured values corresponds to large error. With the introduction of the imaginary component of impedance, a somewhat equivalent of resistance for capacitors and inductors, analyzing circuitry has become much easier. Also, with this experiment, we are able to see how exactly this element influences the circuit. All in all, this lab did exactly what it was supposed to, and we were able to show the connections between our measured and theoretical data.

    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.
