6-2. R-C, R-L serial/parallel circuit

① Set the circuit as shown fig 3-17. Then draw its graph in the following table.

- Differential circuit with square wave & Differential circuit with sinusoidal wave

⑤ Set the circuit as shown in fig 3-19, and modify R to let Lissajous` figure have 45° phase. Measure R at that moment, then calculate inductance L.

⑨ Set the circuit as shown in fig 3-22, and adjust R to let Lissajous figure have 45° phase. Calculate the capacitance(C) by measuring R.


For setting value of inductance 2.2mH, R is measured as 1.601kΩ which makes Lissajous` figure. The theoretical value of R is 1.5923kΩ. So there is error ratio -0.54%.

6-3. R-C-L serial/parallel response circuit
To measure the frequency precisely that Vx=0 (or minimum) and Vx=VR. This is called resonance frequency. As we measured that the value was 10.21[kHz]. It is a little gap with ideal value of resonance frequency. Therefore the difference with theoretical value and experimental value should be happened by the experiment environment and internal resistance of the electric device.
