Ko te uara parenga iahiko - ara o te tuhi

Parenga - nga mea timatanga o iahiko hiko he ātete ki te wahi o te nāianei hiko. E whakamahia ratou i roto i iahiko katoa, ara i roto i te timatanga tino. Wehewehe parenga i te āhuatanga e whai ake nei: te mana i te ātete ränei o te piha haapiiraa o te tika o te ngakau, etc. I roto i tenei tuhinga, ka whakaaro matou he mea pēnei i te uara resistance.. He aha te mea te reira? I raro i te hāhi o te huānga ātete te tikanga uara taumata o parenga ā o te wahi o te therethrough nāianei hiko. denoted te uara ārai hiko e Latin pukapuka R. Kei te nuinga o tenei uara i tuhituhia i roto i taua waeine, rite Om. te ingoa tenei kōwae i muri i te rongonui ahupūngao Tiamana Georg Haimona Ohm, mohiotia hoki tona mahi i roto i te mara o te nāianei hiko. He aha e hiahia ana koe ki te mohio i te uara o parenga? He aha koe e whiriwhiri i te āhuatanga tika hoki te kaupapa hangaia ki te tiki ake i te tairitenga o te pūrere hanga.

A feruri i tikanga tuhi uara ātete iti i runga i te huānga whare. E toru ara o tohu parenga: Digital - ngā tau anake; pūāhua - ko te ngā, me nga tau, me pukapuka he hakari; a te mutunga tae - ko te raupapa o ropu hake o tae rerekē, he rerekē te maha o huarahi, i 3 ki te 5.

I tua atu tātari rite uara parenga iahiko tuhia i runga i te momo o te huānga rānei. ātete tamau āhuatanga waea-momo he porotakaroa oko. Tohua e taua āhuatanga i roto i te ara katoa e toru. Kei te whakamahia anake te tuhi Digital mo parenga, te uara o te uara iti o e kore e nui ake 999 ohms. titiro reira e whai ake: 2.0; 220; 750. Founga aua 2 ohms, 220 ohms me 750 ohms. whakamahi momo tuhi i muri he reta piko o te tātai reta Latin: R - ko te wae; K - he kiro, arā 1000; M - mega, arā, 1000000. Huri i te reira i roto i taua ki tenei tikanga tuhi, i roto i te tikanga ki te tiki i te uara parenga me waiho he uara tau whakanuia e te uara o te mau. He tauira o te lekooti taua 220 R - 220 ohms tikanga; 3K2 - te tikanga 3200 ohms; 1M1 - tikanga 1100 ohms.

tono Tae waehere o te uara te tauanga te puta noa te tuhi o te mema tinana porotakaroa. Ko te parenga Soviet-hanga tohu i tono ki te wāhikē ki tetahi taha, tohu te reira i te takenga o te wetewaehere. I roto i ngā āhuatanga hou ropu tonu whakamutunga waehere pae koura hiriwa ranei, a te auraa te piha haapiiraa resistance tika (5 ranei 10 ōrau). I roto i te kaupapa e ngā te māka o toru anake here, te auraa te piha haapiiraa kātakí taunoa te 20 ōrau. Kei Whakawaehere o 3-4 here i roto i te uara tuatahi e rua Kei te uara ränei, me te tuatoru - te uara o te whakanui. Whakawaehere o 5-6 here i roto i te uara tuatahi e toru ngā te ränei, me i roto i te wha - te uara o te whakanui.

Tiro Next resistance - he parenga kongakonga he SMD-parenga iahiko ranei. I roto i taua parenga tohu he tau, me te tohu. Ia tika tu: i roto i te mamati tohu i te mati tuatahi tohu te uara ränei, me te whakamutunga i te maha o ngā kore; i roto i te huru - tohu nga mati tuatahi e rua te hāhi, me te huru whakamutunga - i te uara o te whakanui.

I roto i te iahiko tāupe , te tuhi paerewa o te uara ränei te whakamahi i ngā tau, me pukapuka o te tātai reta Latin.
