1.
Dziwani mphamvu yamagetsi mu dera (1 µF = 10 -6 F)
Zodziwika:
Wotsutsa (R) = 12 Ohm
Inductor (L) = 0.075 H
Capacitor (C) = 500 µF = 500 x 10 -6 F = 5 x 10 -4 Farad
Vol oltage (V) = Vo o sin ω t = Vo o sin 2πf t = 26 sin 200t
Kufunidwa: Mphamvu yamagetsi
Yankho:
Kusakhazikika (Z):
Kuyankha koyambitsa (X L ) = ωL = (200)(0,075) = 15 Ohm
Kuyankha kwa capacitive (X C ) = 1 / ωC = 1 / (200)(5 x 10 -4 ) = 1 / (1000 x 10 -4 ) = 1 / 10 -1 = 10 1 = 10 Ohm
Wotsutsa (R) = 12 Ohm
Mphamvu yamagetsi (I) :
I = V / Z = 26 Volts / 13 Ohms
I = 2 Volts/Ohm
I = 2 Amp
2. Ngati kukana kwa dera ndi 250 Ω, dziwani kukana kwa resistor R.
Zodziwika:
Kulephera kwa dera (Z) = 250 Ω
Chotengera (C) = 8 m F = 8 x 10 -6 F
Inductor (L) = 0.8 H
Volti (V) = 200 Volti
w = 500 rad/s
Kufunidwa: Kukana kwa wotsutsa (R)
Yankho:
3. Dziwani kusiyana komwe kungachitike pakati pa mbali zonse ziwiri za inductor.
Zodziwika:
R = 40 W
X L = 150 W
X C = 120 W
V = 100 Volt
Kufunidwa: kusiyana komwe kulipo
Yankho:
Chiwerengero chonse cha impedance Z cha dera:
Kusiyana komwe kungatheke pakati pa mbali zonse ziwiri za inductor:
