电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)是(shi)一(yi)(yi)(yi)种能(neng)贮存电(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷的(de)(de)(de)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)。它(ta)是(shi)由(you)两片靠得较近的(de)(de)(de)金属片,中(zhong)间再隔以(yi)绝(jue)缘物质而构成的(de)(de)(de)。按(an)绝(jue)缘材料不一(yi)(yi)(yi)样,可制成各式各样的(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)。如:云(yun) 母、瓷介、纸介、电(dian)(dian)(dian)(dian)(dian)(dian)(dian)解电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)等。在(zai)构造上,又分为固(gu)定电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)和(he)可变电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)。电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)对直流(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻力无(wu)穷大,即电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)具有隔直流(liu)(liu)效果。电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)对交(jiao)流(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)阻力受交(jiao) 流(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)频(pin)率影响,即一(yi)(yi)(yi)样容(rong)(rong)(rong)量的(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)对不一(yi)(yi)(yi)样频(pin)率的(de)(de)(de)交(jiao)流(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)呈现不一(yi)(yi)(yi)样的(de)(de)(de)容(rong)(rong)(rong)抗。为开(kai)么会呈现这(zhei)些(xie)表象呢(ni)?这(zhei)是(shi)因为电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)是(shi)依托(tuo)它(ta)的(de)(de)(de)充(chong)放电(dian)(dian)(dian)(dian)(dian)(dian)(dian)功能(neng)来(lai)工作的(de)(de)(de),电(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)开(kai) 关s 未合上时。电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)的(de)(de)(de)两片金属板(ban)(ban)(ban)和(he)其它(ta)一(yi)(yi)(yi)般金属板(ban)(ban)(ban)一(yi)(yi)(yi)样是(shi)不带(dai)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)。当开(kai)关S合上时,电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)正(zheng)极(ji)板(ban)(ban)(ban)上的(de)(de)(de)自(zi)由(you)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)子便被电(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)所吸引,并推送到负极(ji)板(ban)(ban)(ban)上面。因为电(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong) 器(qi)(qi)(qi)(qi)两极(ji)板(ban)(ban)(ban)之(zhi)距离(li)有绝(jue)缘材料,所以(yi)从正(zheng)极(ji)板(ban)(ban)(ban)跑过来(lai)的(de)(de)(de)自(zi)由(you)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)子便在(zai)负极(ji)板(ban)(ban)(ban)上面堆积(ji)起来(lai)。正(zheng)极(ji)板(ban)(ban)(ban)便因电(dian)(dian)(dian)(dian)(dian)(dian)(dian)子削(xue)减(jian)而带(dai)上正(zheng)电(dian)(dian)(dian)(dian)(dian)(dian)(dian),负极(ji)板(ban)(ban)(ban)便因电(dian)(dian)(dian)(dian)(dian)(dian)(dian)子逐步添(tian)加而带(dai)上负电(dian)(dian)(dian)(dian)(dian)(dian)(dian)。
