E maualuga le malosi ma le ma'a'a'a, fa'aulu eletise ma fa'avevela vevela, lelei fa'alavalava ma fa'aitiitiga fa'aitiitiga.A maeʻa togafitiga matua, o le maaa, malosi, eletise eletise ma le vevela e faʻaleleia atili, ma e faigofie ona faʻafefe.Fa'aaoga lautele i afi commutators, va'aiga uelo, su'isu'i uelo, electrodes mo uelo butt, ma isi vaega e mana'omia le malosi, ma'a'a, conductivity, ma meatotino pad i le vevela maualuga.O le eletise aloiafi e mafai ona faʻaaogaina e faʻapipiʻi ai se faʻata lelei, ma i le taimi lava e tasi, o loʻo i ai le faʻatinoga saʻo lelei, ma e mafai ona ausia aʻafiaga e faigata ona ausia i le apamemea mumu mama e pei o fasi fasi pepa.E fa'atino lelei i mea faigata-i-masini e pei ole sila tungsten.
