Fa'amatalaga o le Oloa
O nei uaea tete'e enameled ua fa'aaogaina lautele mo resistors masani, ta'avale
vaega, tete'e o uili, ma isi mea fa'apena e fa'aaogaina ai le faiga o le insulation e sili ona fetaui ma nei fa'aoga, ma fa'aogaina atoatoa ai uiga tulaga ese o le ufiufi o le enamel.
E le gata i lea, o le a matou faia le ufiufi enamel o uaea u'amea taua e pei o le siliva ma le platinum pe a oka mai. Fa'amolemole fa'aaoga lenei oloa-i-le-oka mai.
