A capacitor chinhu chemagetsi chinoshandiswa kuchengetedza simba remagetsi. Iyo ine mahwendefa maviri ekufambisa akaparadzaniswa nechinhu chinodzivirira chinonzi ** dielectric **. Kana mhepo inoshandiswa kune capacitor, munda wemagetsi unogadzirwa pakati pemahwendefa, uchibvumira capacitor kuchengetedza simba.
Iyo Capacitor Inoshanda
1. Kuchaja:
Kana magetsi akaiswa pamaterminal capacitor, charge inounganidza pamahwendefa. Imwe ndiro inounganidza positive charge, imwe yacho ichitora negative charge. Iyo dielectric zvinhu pakati pemahwendefa inodzivirira kubhadharisa kuyerera zvakananga kuburikidza, kuchengetedza simba mumunda wemagetsi wakagadzirwa. Kuchaja kunoenderera kusvika iyo voltage kuyambuka capacitor yakaenzana neiyo yakashandiswa voltage.
2. Kubvisa:
Kana iyo capacitor yakabatanidzwa kune dunhu, iyo inochengeterwa mutero inoyerera ichidzoka kuburikidza nedunhu, ichigadzira ikozvino. Izvi zvinosunungura simba rakachengetwa kumutoro wedunhu kusvikira mutero wapera.
Hunhu Hunokosha hweCapacitors
- Capacitance:
Kugona kwecapacitor kuchengeta charge kunonzi capacitance, kuyerwa nefarads (F). A hombe capacitance zvinoreva thecapacitorinogona kuchengeta mari yakawanda. Iyo capacitance inokonzerwa nepamusoro penzvimbo yeplateti, kureba pakati pavo, uye zvinhu zve dielectric material.
-Kuchengetedzwa Kwesimba:
Macapacitor anoita semidziyo yekuchengetedza yenguva pfupi yemagetsi emagetsi, akafanana nemabhatiri asi akagadzirirwa kushandiswa kwenguva pfupi. Ivo vanobata nekukurumidza shanduko yemagetsi uye inotsvedzerera kunze kuchinjika, zvichibatsira kune yakagadzikana kushanda kwedunhu.
- Leakage Yazvino uye Yakaenzana Series Resistance (ESR):
Capacitors inosangana nekurasikirwa kwesimba panguva yekuchaja uye kuburitsa madhiri. Leakage current inoreva kunonoka kurasikirwa kwechaji kuburikidza ne dielectric material kunyangwe isina mutoro. ESR ndiko kupikisa kwemukati kunokonzerwa nezvinhu zviri mukati me capacitor, inokanganisa kushanda kwayo.
Inoshanda Zvishandiso zveCapacitors
-Kusefa:
Mumagetsi emagetsi, ma capacitor anoita semafirita ekutsvedzerera kushanduka kwemagetsi uye kubvisa ruzha rusingadiwe, kuve nechokwadi chekudzika kwevoltage kubuda.
- Kubatana uye kubatanidzwa:
Mukufambisa kwemasaini, ma capacitor anoshandiswa kupfuudza masaini eAC achivhariraDC zvikamu, kudzivirira DC kuchinja kubva pakukanganisa kushanda kwedunhu.
-Kuchengetedzwa Kwesimba:
Macapacitor anochengetedza uye anoburitsa simba nekukurumidza, zvichiita kuti abatsire mukushandisa senge kupenya kwekamera, maturusi emagetsi, uye zvimwe zvishandiso zvinoda kuputika kupfupi kweazvino.
Summary
Macapacitor anoita basa rakakosha mumaseketi emagetsi nekuchengetedza uye kuburitsa simba remagetsi. Vanobatsira kudzora voltage, kuchengetedza simba, uye kubata masaini. Kusarudza iyo chaiyo mhando uye kutsanangurwa kwecapacitor kwakakosha pakuve nechokwadi chekuita uye kuvimbika kwemaseketi emagetsi.
