The ike nke capacitor na ya ikike

Ọ bụrụ na abụọ ụgwọ akụkọ abụọ gwara mmanụ na-eduzi, n'etiti ha n'ebe ahụ a na-akpọ nwere ihe dị iche, nke na-adabere na ịdị ukwuu nke na-anaghị ego jiometrị nke na-eduzi. Na ikpe, ma ọ bụrụ na ebubo ndị hà na ịdị ukwuu ma abụghị na ihe ịrịba ama, ị nwere ike tinye definition nke capacitance, site na nke i nwere ike ahụ ga-esi a echiche nke otú ike nke capacitor. Eletriki capacitance nke usoro esịnede abụọ na-eduzi, na-ruru nke otu n'ime ebubo ka nwere ihe dị iche n'etiti-eduzi.

The ike nke capacitor adabere capacitance. Ọ nwere ike na-ekpebisi ike site mgbawa nke a ruru. The ike nke capacitor (usoro) ga-ọnọde yinye:

W = (C * U * U ) / 2 = (q * q) / (2 * C) = q * U / 2, ebe W- ike nke capacitor C bụ capacitance, U- nwere ihe dị iche n'etiti abụọ efere (voltaji) , q- uru nke ụgwọ ego.

The uru nke capacitance na-adabere na size na udi nke na-eduzi na dielectric na-ekewa ndị a na-eduzi. A usoro nke electric ubi na-lekwasị (metụtara nanị akụkụ ụfọdụ) naanị na a na-ebe, na-akpọ a condenser. The na-eduzi na-eme ka ngwaọrụ na-akpọ efere. Nke a bụ mfe imewe nke a na-akpọ ukem-efere capacitor.

Ndị kasị mfe ngwaọrụ - abụọ ewepụghị efere na-enwe ike na-eduzi ihe eletrik. Ndị a efere mere ndokwa na ukem on a (dịtụ obere) anya n'ebe onye ọ bụla ọzọ na-iche site na a oyi akwa site na insulator. Ubi ike nke capacitor na nke a na-na-metụtara nanị akụkụ ụfọdụ tumadi n'etiti efere. Otú ọ dị, nso n'ọnụ nke efere na a gbara ya gburugburu uwa emee o nnọọ ike radieshon. Ọ na-akpọ na akwụkwọ nke chụsasịrị ubi. N'ọnọdụ ka ukwuu, ọ kpebiri ileghara ha na-eche na ike nile nke capacitor bụ kpam kpam n'etiti efere. Ma mgbe ụfọdụ ọ na-ka na-sonye na akaụntụ (tumadi iji ikpe mikroemkostey ma ọ bụ, ọzọ, Ultra-).

Electric capacitance (n'ihi ya, ike nke capacitor) na-adabere na efere. Ọ bụrụ na anyị na-elegara usoro C = E0 * S / d, ebe C- capacitance, E0- ịdị ukwuu ụkpụrụ nke ndị dị otú ahụ oke dị ka dielectric mgbe nile (na nke a, agụụ) d- uru na anya n'etiti efere, ọ bụ omume na-eme ka a doro anya ọgwụgwụ na capacitance nke ndị dị otú ahụ a ụgbọelu capacitor bụ inversely proportional ka uru nke anya n'etiti efere na bụ ihe ra nrata nye ha ebe. Ọ bụrụ na ndị mbara n'etiti electrodes mezue ụfọdụ kpọmkwem dielectric, mgbe ahụ ike nke capacitor na ya ikike ga-amụba ka E ugboro (E na nke a - na dielectric mgbe nile).

N'ihi ya, anyị nwere ike ugbu a na-egosipụta usoro na nwere ike, nke accumulates n'etiti abụọ electrodes (efere) nke capacitor: W = q * E * d . Otú ọ dị, ọtụtụ mfe iji gosi na echiche nke "ike capacitor" site ikike: W = (C * U * U) / 2.
