Rauemi kaha hiko (EMF) raupapa me te whakarara
Mena e rua, neke atu rānei i te rua ngā pūtake hiko (emf) e honoa ana pērā i te pikitia i te taha, ka honoa raupapa te emf.
Ko te pūtake ngaohiko whakakapinga ( ε ) ko:
ε = ε 1 + ε 2 + ε n
Ko te ātete i roto i te whakakapinga (r) ko:
E ai ki te Ture Tuarua a Kirchhoff, ko te tapeke o ngā huringa o te pūmanawa hiko huri noa i tētahi ara iahiko kati he kore. Ko te Ture Tuarua a Kirchhoff e ahu mai ana i te ture tiaki pūngao, e kī ana he mea tiaki te pūngao.
Hei mārama ake i tēnei, whakaarohia he hiko e neke ana i roto i tētahi ara iahiko kati, pērā i te ahua kei te taha matau. Ina utu hiko haere mā roto i tētahi ātete hiko (R), ka heke te kaha hiko nā te mea ka pau i roto i te ātete. Mēnā ka haere te utu hiko mā roto i tētahi atu ātete hiko, ka heke anō te kaha hiko nā te mea ka pau anō i roto i taua ātete. Hei tāpiri, ina haere te utu hiko mā roto i tētahi pūtake ngaohiko hiko mai i te kaha iti ki te kaha teitei, ka piki ake te kaha hiko. Ina hoki ki tōna pūwāhi taketake, pūngao pūmanawa hiko pērā anō i mua, arā, ko te huringa o te pūngao pūmanawa hiko he kore. Ina whakamahia te ture tuarua a Kirchhoff ki tētahi ara iahiko hiko, ka whakamahia e tātou te huringa o te ngaohiko hiko, ehara i te huringa o te pūngao pūmanawa hiko.
Ko te ture tuatahi a Kirchhoff, e mōhiotia ana ko te ture pūwāhi peka, e kī ana ko te iahiko e tomo ana ki tētahi pūwāhi peka he rite tonu ki te iahiko e wehe atu ana i taua pūwāhi peka. Ko te pūwāhi peka i roto i tētahi ara iahiko hiko he pūwāhi e tūtaki ai ngā kaiārahi e rua, neke atu rānei. pērā i te pūwāhi A i te pikitia i te taha.
Ko I te iahiko e tomo ana ki te pūwāhi peka, ko I 1 me I 2 ia ngā iahiko e wehe atu ana i te pūwāhi peka, I = I 1 + I 2. Hei tauira anō, mātakitakina te ahua i raro nei.
Te ātete o te kaha hikohiko (EMF) i roto i te ngaohiko pito
Ka rere te iahiko hiko i roto i tētahi ara iahiko kati, mai i te pūmanawa teitei ki te pūmanawa iti. Ina neke te iahiko hiko mā roto i tētahi wāhanga o te ātete hiko , ka heke te kaha pūmanawa hiko nā te mea ka whakamahia te kaha hiko i roto i te ātete. Hei whakarite kia rere tonu te iahiko hiko mai i te pūmanawa teitei ki te pūmanawa iti, me whai taputapu hei whakanui ake i te kaha pūmanawa hiko, pērā i te kaha hikohiko (EMF), he tika ake rānei, he pūtake ngaohiko hiko. Ko te EMF, he pūtake ngaohiko hiko rānei, he wāhanga e huri ana i tētahi momo kaha ki te kaha hiko, hei tauira he pākahiko, he kaiwhakaemi, he pūtau rā, he whakaputa hiko rānei.
