VI – 1. For parts 1,2 of Procedure, you measured the phase differ between the current and voltage across L,C. Report sketches of measured signals and your calculated phase differences. Are these as expected? (The manual says it should be 90 degrees) R-C: f: 1000Hz R: 6000Ω C:0.002μF Report the sketches of measured signals and your calculated phase differences. Phase Diff=(l/L) X 360 =(1.5/6.2) X 360 = 87.1 degree R-L: F:1000Hz R: 6000Ω Phase Diff=(l/L) X 360=(1.4/6.2) X 360 = 81.3 degree Yes, graphs are expected features as in manual 90 degree though it does not have exactly same value of degree. VI – 2. Analyze the data from V – 3. For each capacitor arrangement with the air-core inductor that you used (e.g. V – 3, V – 4, V – 5 as appropriate) you should plot the current as a function of frequency. From each resonant frequency you should obtain a calculated value of the inductance and an estimate of the uncertainty in that inductance value. Explicitly state and explain your estimates for uncertainty in all terms (e.g. fR , C etc.) in the equation for L. R-L-C R inductor = 80.75 kΩ (measure for 10k turn!)
