我想問第四題
第一小題看起來像是戴維寧
第二小題看不懂...

因為低頻,所以1/wc=Xc,w=0,Xc=無限大,就開路了

為何電壓會是0伏,這一點很不好喔!他會中間可以等效接地,
就是因為對稱!你先回答我,我把串聯的R跟C像我上面說的拆
開,兩兩分組!這樣我從外面去量阻抗,會有差嗎?所以拆開一
定沒有錯,這就是等效的觀念!其實是電路學的觀念!你一定

就是你的盲點!我們先不管中間電壓!我先問你,對半拆開沒
錯,那左右兩邊是否完全對稱?如果是!我為何不能中間等效
接地!懂了嗎?你一直拘泥在電阻跟電容中間為何是0伏,這點
就”很不健康”!

是交流就沒有中間接地 因為不是阻抗 不會吃一半電壓 但
重點是中間不會放電流源 因為不是從那偏壓的
