Fa'amatalaga Lautele

O le uaea o le ogaumu eletise o se ituaiga uaea eletise e maualuga le tete'e. E tete'e le uaea i le tafe o le eletise, ma liua le malosiaga eletise i le vevela.

O le fa'aoga o uaea tete'e e aofia ai resistors, elemeni fa'avevela, fa'avevela eletise, ogaumu eletise, toasters, ma le tele o isi mea.

O le Nichrome, o se u'amea e le fa'amaneta o le nickel ma le chromium, e masani ona fa'aaogaina e fai ai uaea tete'e ona e maualuga lona tete'e ma le tete'e atu i le fa'a'okesaita i le vevela maualuga. A fa'aaogaina o se elemene fa'avevela, e masani ona fa'apipi'i le uaea tete'e i totonu o ni uaea. O se tasi o faigata i le fa'aaogaina o le Uaea Ogaumu Eletise o le le pipii i ai o le solder eletise masani, o lea e tatau ai ona faia ni feso'ota'iga i le eletise e fa'aaoga ai isi auala e pei o ni fa'amau fa'apipi'i po'o ni fa'amau fa'apipi'i.

O le FeCrAl, o se aiga o uʻamea-chromium-alumini e faʻaaogaina i le tele o ituaiga teteʻe ma faʻaoga i le vevela maualuga, e faʻaaogaina foʻi i foliga o uaea teteʻe.
