uiga koluma o le a sili ona fiafia i ai ma sili atu ona popolega e uiga i tagata fou fou!
O faʻamatalaga mulimuli nei o faʻamatalaga autu mo matāʻupu taua faʻapitoa:
Solitulafono Faʻamasaga poʻo le IR e pei ona taʻu mai e le igoa o le tetee o
o le mea faʻamama IR puipuia moni mea eletise mai puʻupuʻu. Taua IR
e masani ona maualuga tele i le tulaga o Mega-ohm poʻo Mohm.
Taugofie o le Laʻu faʻamoemoe pe o le dielectric o le Vasega 1 poʻo le Vasega 2. O le keramika
capacitor (aemaise le vasega 2) e masani ona i ai le maualuga faʻasologa mea, maualuga maualuga coefficient o faʻasalaga.
Faʻaleaogaina itu (tan δ):poʻo le DF ua faʻamatalaina o le fua faʻatatau o le ESR ma capacitive reactance. O le
dissipation itu e taʻua foi o le tangent o le leiloa itu ma e masani ona faʻaalia i le pasene.
Faʻailoaina tulaga faʻatulagaina faʻaalia le dissipation mea i faʻapitoa taimi masani 120Hz mo Alumini
electrolytic ma Tantalum capacitors ao mo tifaga capacitors o 1 kHz ma le 1 MHz mo capacitors keramika.
Faʻasalaga Faʻapitoa (PD): o se eletise eletise poʻo se aloiafi e faʻasolo se vaega itiiti o le faʻamalama
i le va o taʻavale eletise e lua .PD e mafai ona tupu i soo se itu i le faʻavavega, pe a fai o le eletise eletise
malosi e sili atu nai lo le malosi o lena vaega o le meaola vaalele.PD e mafai ona tupu i totonu o le vaalele i totonu
faʻamalosi faʻamalosi, i luga o le fogaeleele o mea e faʻamalosia ai ona o mea e afaina ai poʻo mea e le faʻaleagaina, i totonu o le gaosiga o le gas
i totonu o le faʻamalolo vai poʻo le va o se eletise i le kesi (gaioiga).
