LRC Series AC Circuit – fa'afitauli ma fofo

1.

Fuafua le tafe eletise i le matagaluega (1 µF = 10 ^-6 F)

Ua iloa:

Tete'e (R) = 12 Ohm

Fa'a'a'a (L) = 0.075 H

Kapasitora (C) = 500 µF = 500 x 10 ^-6 F = 5 x 10 ^-4 Farad

Voltage (V) = V _o sin ω t = V _o sin 2πf t = 26 sin 200t

Manaomia: Tafe eletise

Fofo:

Fa'alavelave (Z):

O le tali fa'aoso (X _L ) = ωL = (200)(0,075) = 15 Ohm

O le capacitive reactance (X _C ) = 1 / ωC = 1 / (200)(5 x 10 ^-4 ) = 1 / (1000 x 10 ^-4 ) = 1 / 10 ^-1 = 10 ¹ = 10 Ohm

Tete'e (R) = 12 Ohm

Tafe eletise (I) :

I = V / Z = 26 Volts / 13 Ohms

I = 2 Volts/Ohm

I = 2 Amp

2. Afai o le impedance o le matagaluega e 250 Ω, fuafua le tete'e o le resistor R.

Ua iloa:

O le impedance o le matagaluega (Z) = 250 Ω

Kapasitora (C) = 8 m F = 8 x 10 ^-6 F

Fa'a'a'a (L) = 0.8 H

Voltage (V) = 200 Volt

w = 500 rad/s

Mana'omia: Tete'ega o le resistor (R)

Fofo:

3. Fuafua le eseesega o le gafatia o pito uma e lua o le inductor.

Ua iloa:

R = 40 W

X _L = 150 W

XC ₌ 120 W

V = 100 Volt

Manaomia: le eseesega o le gafatia

Fofo:

O le aofaʻi atoa o le impedance Z o le matagaluega:

O le eseesega o le gafatia o pito uma e lua o le inductor:
