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.

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 "
