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)
RC:
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
RL:
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 aircore
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.
