Electrical capacitance of capacitor: mamiriro uye chikuru unhu

Vose vari bhizimisi uye muupenyu hwezuva nezuva kazhinji zvinoda kusikwa hombe nhamba akanaka uye akaipa pamusoro mhosva yemagetsi. Zviri pachena kuti pamwe magetsi mitumbi uye kuti electrostatic induction kuti hazviiti. Zvakaratidza kuti unofanira kuva mudziyo unokosha. mudziyo kwakadaro anoshumira condenser.

The capacitor uri nyore gadziriro raiumbwa dielectric raiparadzanisa kwamahwendefa maviri. Zvakakosha chaizvo kuti pakukora ari insulator yaiva duku zvichienzaniswa kukura izvi chete nemahwendefa, kureva conductors.

Nyore chimiro zvemagetsi capacitive mudziyo uri munhu sandara capacitor, inova chisinganzwisisiki zviviri kwamahwendefa simbi akaparadzaniswa pedyo dielectric. Kana mahwendefa aya kutora Magetsi, ari quantitative kukosha kusungika yomuka pakati yemagetsi munda kusvika kaviri kupfuura chete kusimba pane imwe mahwendefa aya.

Anokosha chokukomborerwa ino ndiyo magetsi capacitance. Electrical capacitance of capacitor tichitarisa Electro bwezvingoro vakaenzana nhamba vebasa rimwe kwamahwendefa kusvika voltage rakaiswa pakati conductors kuti mudziyo uyu. Kazhinji, magetsi capacitance pamusoro capacitor riri sezvinotevera:

C = Q / U

Kana nzvimbo kwamahwendefa muchadenga anoramba kuchinja kwenguva refu, magetsi capacitance pamusoro capacitor inoramba kugara (pasinei quantitative vebasa Panhivi).

Mune International System pakati kuyerwa zvemagetsi capacitance pamusoro capacitor hwomuviri unotaurwa farads (F). Maererano kupatsanura ichi, mumwe farad chinoratidzwa zvemagetsi capacitance mumwe mudziyo yakadaro umo voltage pakati insulators ndomumwe volt, uye uwandu muripo iyo rinoshandisirwa ndiro, akaenzana imwe pendant.

Kutaura zvazviri, imwe farad - iri guru chaizvo kukosha, saizvozvo vazhinji inowanzoshandiswa zviumbu dzakadai microfarad, uye kunyange Nanofarad PF.

Flat zvemagetsi capacitance yacho capacitor achavaponesa nzvimbo electrodes ayo uye achawedzerwa apo achidzikisa kure pakati pavo. To yekudyidzana kuwedzera zvemagetsi vachikwanisa mano aya pakati conductors hunosumwa kana mumwe dielectric.

Kazhinji, kuti electrodes nokuti capacitors kubva nhete foil uye gasket sezvo panozogadzirika inoshandiswa bepa, Mika kana zvedongo. Ndizvo maererano zvinhu kushumira sehwaro nokuda dielectrics, capacitors, uye kuwana zita ravo - bepa, zvedongo, mhepo, Mika. Kumbonyanya kupararira mumakore achangopfuura vakagamuchira electrolytic capacitors kuti vari zvakakwana tsindirana kukura vane yakawanda yemagetsi vanokwanisa. Nekuda izvi unhu, vari zvinowanzoshandiswa mhuri midziyo yemagetsi, uyewo rectifier kuitika.

Capacitors tiri chimwe chezvinhu zvinokosha midziyo yemagetsi, pasina izvo zvaizova hazvitomboiti kuti ruzhinji dzeimba uye midziyo yemagetsi.
