Polar tester mpaka 6 volts

Nthawi zambiri zimachitika kuti ndikofunikira kudziwa polarity wa mphamvu yamphamvu iliyonse. Ndidapanga yankho pavuto kwa iwo omwe alibe mathupi. Ichi ndi cholembera polarity pa malo anayi. Apa ndi mawonekedwe ake, ndizochepa kwambiri, motero zimatenga malo pang'ono ndipo zimangowonekera pakalibe zida zapadera.

Tithana ndi tsatanetsatane

Tikufuna:

-Digal 4 ma PC. (Moden 1n4001 kapena Analogues: 1n4004, 1N4005, 1N4007);

-Slodisodisod ofiira ndi wobiriwira;

-Remprovistor pa 1kom;

- mawaya;

-Kugwiritsa ntchito ndalama zolimba;

Tithana ndi chiwembu, ngati mukufuna kupanga wolamulira mpaka 3 Volts, ndiye kuti zingachotsedwe ku chiwembu:

Koma timakambirana mwachindunji momwe tingapangire oyesa ma volts 6

Pitani ku msonkhano

Kuyamba ndi, kukhazikitsa ma LED

Kenako muyenera kuyika mitsinje ya ma LED

Kupitilira apo, malinga ndi chiwembu, timaphatikiza zonsezo ndikupeza njira ya 3-volt tyer

Koma ntchito yathu ndikupanga tester 6-volt, motero, kutsatira chiwembucho, dulani

Chotsatira, timatupa mawanga osiyanasiyana, ndipo chilichonse chitha kuyesedwa.

Asanayesedwe, timadziwa kuti ndi chitide chomwe chimatsimikizira polarity. Timatenga batri, kudziwa chipongwe chake, ndikulumikizana ndi wonyoza. Zomwe LED idzayatsidwa (ngati mulumikiza mawaya moyenera: ofiira ndi "" ndi zakuda ndi "-"), iye amatanthauza kuti polarity amawonedwa molondola.

Mfundo yochita ndi yosavuta pomwe polarity imawonedwa moyenera (waya wakuda pa "minus", ndi waya wofiira pa "kuphatikiza" zomwe zimasankhidwa " ena adzayatsa.

Ndili ndi "kutanthauzira" kofiyira "

Ndi zobiriwira zikuwonetsa kuti polarity siyimitsidwa

Nawo, ngati ndinu eyakale yailesi yoyambira, ndiye ndikulimbikitsa kuti mtolankhani uyu, udzathandizira polojekiti amtsogolo, komanso mwachitsanzo, mutha kumvetsetsa mfundo za kugwirira ntchito ma diodive :)
