1. A na-egosipụtakarị capacitor site na "C" gbakwunyere nọmba na sekit (dị ka C13 pụtara capacitor nọmba 13). Capacitor mejupụtara ihe nkiri igwe abụọ dị nso na ibe ya, kewapụrụ ya site na ihe mkpuchi n'etiti. Njirimara nke capacitor bụ Ọ bụ DC ka AC.

Ọnụ ọgụgụ nke ikike nke ike bụ ọnụọgụ eletrik nke nwere ike ịchekwa. A na-akpọ mmetụta nkwụsị nke capacitor na mgbaàmà AC capacitive reactance, nke metụtara ugboro na ike nke AC mgbaàmà.

Capacitance XC = 1/2πf c (f na-anọchi anya ugboro nke akara AC, C na-anọchi anya ike)

Ụdị capacitors ndị a na-ejikarị na ekwentị bụ electrolytic capacitors, ceramic capacitors, mgbawa capacitors, monolithic capacitors, tantalum capacitors na polyester capacitors.

2. Usoro njirimara: Usoro njirimara nke capacitor bụ otu ihe ahụ dị ka usoro njirimara nke resistor, nke kewara n'ime atọ: usoro ọkọlọtọ kwụ ọtọ, usoro agba agba na usoro ọnụọgụ nọmba. Isi nkeji nke capacitor bụ Farah (F), na nkeji ndị ọzọ bụ: millifa (mF), microfarad (uF), nanofarad (nF), picofarad (pF).

N'ime ha: 1 farad = 103 millifarad = 106 microfarad = 109 nanofarad = 1012 picofarad.

A na-akara uru ikike nke nnukwu ikike ikike na capacitor, dị ka 10 uF / 16V

Ọnụ ahịa ikike nke capacitor nwere obere ikike bụ mkpụrụedemede ma ọ bụ ọnụọgụ dị na capacitor nọchiri anya ya.

Nkọwa akwụkwọ ozi: 1m = 1000 uF 1P2 = 1.2PF 1n = 1000PF

Nnọchite anya dijitalụ: N'ozuzu, a na-eji ọnụọgụ atọ gosi nha ike, ọnụọgụ abụọ mbụ na-anọchi anya ọnụọgụ dị ịrịba ama, na nke atọ bụ mmụba.

Dịka ọmụmaatụ: 102 pụtara 10 × 102PF = 1000PF 224 pụtara 22 × 104PF = 0.22 uF

3. Njehie table nke capacitance

Akara: FGJKLM

Njehie ekwe ekwe ± 1% ± 2% ± 5% ± 10% ± 15% ± 20%

Dịka ọmụmaatụ: seramiiki capacitor nke 104J na-egosi ikike nke 0.1 uF na njehie nke ± 5%.
