What do each of the fitting parameters represent? This fit is a more precise way of ob- taining both ω and τ than in the previous sections. The over-damped signal is simpler than the under-damped one. Save your data. Fit it to the following, mathematical expression with fitting parameters A and B: V ( t ) = Ae - Bt/ 2 (2) Again, what do each of the fitting parameters represent? Is the value you get for τ con- sistent with what you calculated theoretically? 1

Critically Damped ...Measure the resistance of the Decade Box using your DMM and determine what the total resistance ( R tot = R dec + R sig + R L ) is for this circuit. This is your empirical value for R crit . Compare this with the theoretical value given by Eq. ?? . Is your value within the expected error? 3 Driven LRC circuit Sweep the driving frequency while watching the amplitude of the V R response. Roughly locate the frequency at which | V R | is maximal. This should correspond approximately to the theoretical value of ω 0 / 2 π . Are the two in agreement with one another? Locate the two “half power” points above and below the resonant frequency; these are the frequencies at which the amplitude of oscillation is V max / 2, where V max is the amplitude at resonance (Fig. ?? ). Since power ∝ | I | 2

    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.
