不可能與頻率完全成正比關(guān)系，其可能有并聯(lián)成分，也可能有串聯(lián)成分，應(yīng)看何種成分占主導(dǎo)。(2)根據(jù)元件的使用情況來(lái)判定。如用于信號(hào)耦合電容，則優(yōu)先選擇串聯(lián)方式，旁路或并聯(lián)諧振則使用并聯(lián)等效電路。習(xí)慣上說(shuō)低阻抗元件用串聯(lián)，從數(shù)值上說(shuō)阻抗小于100歐姆一定用串聯(lián)，大于10千歐用并聯(lián)，(100歐姆-10千歐)根據(jù)實(shí)際情況選擇。佛山數(shù)字式lcr測(cè)量?jī)x</p><p
