  1. RLC串聯電路

  2. 示波器 Ch1 可變電阻 函數產生器 範圍 ~kHz A 實驗A:共振曲線 共振曲線 半寬值比 (fractional half-width) =△ω / ω =△f / f 改變頻率,記錄電流的大小,畫出曲線,找出共振頻率(fr)及半寬值。並找出 f1/2 改變電阻值,重複前一步驟。

  3. 實驗B:觀察電阻、電容和電感,每兩者之間的相位差實驗B:觀察電阻、電容和電感,每兩者之間的相位差 示波器 Ch1 示波器 Ch2 可變電阻 函數產生器 範圍 ~kHz 頻率選在共振頻率(fr)。 畫出示波器上所看到之二者波形(Dual)、李賽圖形(X-Y) ,由此判斷VR和VC的相位差,及畫出phasor。並和課本比較。(畫圖時請將橫軸刻度標示清楚) 示波器改接到電容和電感二端,重複前一步驟。 頻率改成非共振頻率(f1/2),重複前面幾個步驟。
