Resistance R, inductance L, uye capacitance C ndiwo matatu makuru ezvikamu uye parameters mudunhu, uye ese maseketi haagone kuita pasina aya matatu paramita (inenge imwe yacho).Chikonzero nei ivo vari zvikamu uye parameters imhaka yekuti R, L, uye C inomiririra rudzi rwechikamu, senge chinopikisa chikamu, uye kune rumwe rutivi, inomiririra nhamba, senge kukosha kwekupokana.
Izvo zvinofanirwa kutaurwa zvakanyanya pano kuti pane musiyano pakati pezvikamu zviri mudunhu uye izvo chaizvo zvemuviri zvikamu.Izvo zvinonzi zvikamu mumutambo chaizvoizvo zvinongova muenzaniso, izvo zvinogona kumiririra humwe hunhu hwezvikamu chaizvo.Zvichitaurwa zviri nyore, isu tinoshandisa chiratidzo kumiririra humwe hunhu hweiyo chaiyo midziyo yemidziyo, senge resistors, mabira emagetsi, etc Magetsi ekudziya emagetsi uye zvimwe zvikamu zvinogona kumiririrwa mumasekete vachishandisa resistive components semienzaniso yavo.
Asi mamwe maturusi haagone kumiririrwa nechikamu chimwe chete, sekumonereka kwemota, inova coil.Zviripachena, inogona kumiririrwa ne inductance, asi mhepo inewo kukosha kwekupokana, saka kuramba kunofanirwa kushandiswawo kumiririra kukosha uku.Naizvozvo, kana uchienzanisira mota inotenderera mudunhu, inofanirwa kumiririrwa neyakatevedzana musanganiswa we inductance uye kuramba.
Resistance ndiyo yakapfava uye inozivikanwa zvikuru.Zvinoenderana nemutemo waOhm, kuramba R=U/I, zvinoreva kuti kuramba kwakaenzana nevoltage yakakamurwa neazvino.Kubva pamaonero ezviyuniti, iri Ω=V/A, zvinoreva kuti ohms yakaenzana nevolts yakakamurwa neampere.Mudunhu, kushorwa kunomiririra kuvharidzira maitiro pane ikozvino.Kukura kwekupikisa, ndiko kusimba kwekuvharisa pazvino… Muchidimbu, kuramba hakuna chekutaura.Tevere, isu tichataura nezve inductance uye capacitance.
Muchokwadi, inductance inomiririrawo simba rekuchengetedza simba rezvikamu zve inductance, nekuti iyo yakasimba iyo magineti, yakakura simba rainaro.Magnetic minda ine simba, nekuti nenzira iyi, magineti anogona kushandisa simba pane magineti mune remagineti uye kuita basa paari.
Ndeupi hukama pakati pe inductance, capacitance, uye kuramba?
Inductance, capacitance pachayo haina chekuita nekupokana, zvikamu zvadzo zvakasiyana zvachose, asi zvakasiyana mumaseketi eAC.
MuDC resistors, inductance yakaenzana nepfupi wedunhu, nepo capacitance yakaenzana nedunhu rakavhurika (yakavhurika dunhu).Asi mumaseketi e AC, zvese inductance uye capacitance zvinogadzira zvakasiyana siyana zvekupikisa ne frequency shanduko.Panguva ino, kukosha kwekupikisa hakusati kuchizonzi kupikisa, asi kunonzi reactance, inomiririrwa netsamba X. Kurwisana kunokosha kunogadzirwa ne inductance kunonzi inductance XL, uye kukosha kwekudzivirira kunokonzerwa ne capacitance kunonzi capacitance XC.
Inductive reactance uye capacitive reactance yakafanana nevanopikisa, uye zvikamu zvavo zviri mu ohms.Nokudaro, ivo vanomiririrawo kuvharidzira maitiro e inductance uye capacitance pane ikozvino munharaunda, asi kupikisa hakushanduki nehuwandu, asi inductive reactance uye capacitive reactance shanduko ne frequency.
