Ia suʻesuʻe foʻi mea e uiga i le teteʻe eletise , faʻataʻitaʻiga o faʻafitauli o le resistor faʻasolosolo , faʻataʻitaʻiga o faʻafitauli o le resistor tutusa.
2 Faʻataʻitaʻiga o Fesili e uiga i le Teteʻe i le Eletise
1. O se masini eletise ua feso'ota'i i se puna eletise e 30 Volt ma e feavea'i se eletise e 2 Amperes. Fuafua le tete'e eletise o le masini!
Talanoaga
Ua iloa e faapea:
Voltage eletise (V) = 30 Volts
Tafe eletise (I) = 2 Ampere
Fesili: Tete'e eletise (R)
Tali:
Fua fa'atatau o le tete'e eletise:
R = V/I
Fa'amatalaga: R = tete'e eletise, V = voltage eletise, I = tafega eletise.
R = 30 Volts / 2 Amps = 15 Volts/Amperes = 15 Ω (faitau: Ohms).
2. Fuafua le tete'e eletise o ni uaea eletise se tele e 1 mita le umi ma le lautele o le vaega fa'alava e 1 x 10 -5 m² . O le tete'e o uaea eletise o lo'o ta'ua i le laulau o lo'o i lalo.
Talanoaga
Fua fa'atatau o le tete'e eletise:
Fa'amatalaga: R = tete'e eletise, ρ = tete'e fa'apitoa, l = umi o le aveta'avale, A = lautele o le vaega fa'alava o le aveta'avale.
