E hoʻoholo i ke au uila i loko o ke kaapuni (1 µF = 10 -6 F)
ʻIke ʻia:
Palekana (R) = 12 Ohm
ʻO ka mea hoʻokomo (L) = 0.075 H
Ka mea hoʻonui (C) = 500 µF = 500 x 10 -6 F = 5 x 10 -4 Farad
Anakahi uila (V) = V o sin ω t = V o sin 2πf t = 26 sin 200t
Makemake ʻia: Au uila
Lōlā:
Ka pale ʻana (Z):
ʻO ka reactance inductive (X L ) = ωL = (200)(0,075) = 15 Ohm
ʻO ka reactance capacitive (X C ) = 1 / ωC = 1 / (200)(5 x 10 -4 ) = 1 / (1000 x 10 -4 ) = 1 / 10 -1 = 10 1 = 10 Ohm
Palekana (R) = 12 Ohm
Au uila (I) :
ʻO I = V / Z = 26 Volts / 13 Ohms
ʻO I = 2 Volts/Ohm
ʻO wau = 2 Amp
2. Inā he 250 Ω ka impedance o ke kaapuni, e hoʻoholo i ke kū'ē o ka resistor R.
ʻIke ʻia:
ʻO ka impedance o ke kaapuni (Z) = 250 Ω
Ka mea hoʻopili (C) = 8 m F = 8 x 10 -6 F
ʻO ka mea hoʻokomo (L) = 0.8 H
Uila uila (V) = 200 Volt
w = 500 rad/s
Makemake ʻia: Ke kū'ē o ke kū'ē (R)
Lōlā:
3. E hoʻoholo i ka ʻokoʻa hiki o nā ʻaoʻao ʻelua o ka inductor.
ʻIke ʻia:
R = 40 W
X L = 150 W
XC = 120 W
V = 100 Volt
Makemake ʻia: ka ʻokoʻa hiki
Lōlā:
ʻO ka huina impedance Z o ke kaapuni:
ʻO ka ʻokoʻa hiki o nā ʻaoʻao ʻelua o ka inductor:
