Rumwe ruzivo nezve Resistance R, inductance L, uye capacitance C

Muchikamu chekupedzisira, takataura hukama pakati peResistance R, inductance L, uye capacitance C, apa tichakurukura rumwe ruzivo nezvavo.

Kana zviri zvekuti nei inductors uye capacitors zvichigadzira inductive uye capacitive reactances mumaseketi eAC, musimboti uri mukushanduka kwevoltage uye ikozvino, zvichikonzera shanduko musimba.

Kune inductor, kana ikozvino kuchinja, iyo magnetic field inoshandukawo (simba rinoshanduka).Isu tose tinoziva kuti mune electromagnetic induction, iyo induced magnetic field inogara ichidzivisa kuchinja kwepakutanga magnetic field, saka sezvo nguva yakawanda inowedzera, mhedzisiro yeichi chipingamupinyi inova pachena, iyo inowedzera inductance.

Kana iyo voltage ye capacitor ichichinja, huwandu hwechaji paplate ye electrode inochinjawo zvinoenderana.Zviripachena, iyo inokurumidza kuchinja kwemagetsi, inokurumidza uye yakawanda kufamba kwehuwandu hwekuchaja pane electrode plate.Kufamba kwehuwandu hwekuchaja ndiyo chaiyo ikozvino.Zvichitaurwa zviri nyore, iyo inokurumidza kuchinja kwemagetsi, iyo yakakura ikozvino inoyerera kuburikidza ne capacitor.Izvi zvinoreva kuti iyo capacitor pachayo ine diki yekuvhara maitiro pane ikozvino, izvo zvinoreva kuti iyo capacitive reactance iri kuderera.

Mukupfupisa, iyo inductance yeinductor yakanyatso kuenzana ne frequency, nepo capacitance ye capacitor iri inversely proportional to frequency.

Ndeupi musiyano uripo pakati pesimba uye kuramba kwemainductors uye capacitors?

Maresistors anoshandisa simba mune ese DC uye AC maseketi, uye shanduko mumagetsi neazvino zvinogara zvakawiriraniswa.Semuenzaniso, chiverengero chinotevera chinoratidza voltage, ikozvino, uye simba macurves ezvipikisi mumaseketi eAC.Kubva pane girafu, zvinogona kuonekwa kuti simba rekudzivirira rave riri guru kudarika kana rakaenzana ne zero, uye harizove riri pasi pe zero, izvo zvinoreva kuti resistor yave ichitora simba remagetsi.

Mune AC circuits, simba rinoshandiswa nevapikisa rinonzi simba repakati kana simba rinoshanda, rinoratidzwa nebhii guru P. Izvo zvinonzi simba rinoshanda rinongomiririra maitiro ekushandiswa kwesimba kwechikamu.Kana chimwe chikamu chine simba rekushandisa, saka kushandiswa kwesimba kunomiririrwa nesimba rinoshanda P kuratidza hukuru (kana kukurumidza) kwekushandisa kwayo simba.

Uye capacitors uye inductors havadyi simba, vanongochengeta uye kusunungura simba.Pakati pavo, inductors inotora simba remagetsi nenzira yekusimudzira magineti, iyo inotora uye inoshandura simba remagetsi mumagetsi emagetsi, uye zvino kusunungura simba remagetsi mumagetsi emagetsi, zvichiramba zvichidzokorora;Saizvozvowo, ma capacitors anotora simba remagetsi uye anoshandura kuva simba remagetsi emagetsi, apo achibudisa simba remagetsi emagetsi uye achishandura kuva simba remagetsi.

Inductance uye capacitance, nzira yekutora uye kusunungura simba remagetsi, haidyi simba uye zvakajeka haigoni kumiririrwa nesimba rinoshanda.Kubva pane izvi, nyanzvi dzefizikisi dzakatsanangura zita idzva, iro reactive simba, rinomiririrwa nemavara Q uye Q.
