Potoloho ea AC ea Letoto la LRC - mathata le litharollo

1.

Fumana motlakase o potolohang (1 µF = 10 ^-6 F)

Tse tsejoang:

Mohanyetsi (R) = 12 Ohm

Motlakase (L) = 0.075 H

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

Tekanyo e phahameng (V) = Vo _o sin ω t = Vo _o sin 2πf t = 26 sin 200t

Ho batloa: Motlakase oa motlakase

Tharollo:

Ho se sireletsehe (Z):

Karabelo ea inductive (X _L ) = ωL = (200)(0,075) = 15 Ohm

Karabelo ea capacitive (X _C ) = 1 / ωC = 1 / (200)(5 x 10 ^-4 ) = 1 / (1000 x 10 ^-4 ) = 1 / 10 ^-1 = 10 ¹ = 10 Ohm

Mohanyetsi (R) = 12 Ohm

Motlakase (I) :

Ke = V / Z = 26 Volts / 13 Ohms

Ke = 2 Volts/Ohm

I = 2 Amp

2. Haeba impedance ea potoloho e le 250 Ω, fumana khanyetso ea resistor R.

Tse tsejoang:

Phetoho ea potoloho (Z) = 250 Ω

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

Motlakase (L) = 0.8 H

Motlakase (V) = 200 Volt

w = 500 rad/s

Ho batloa: Khanyetso ea khanyetso (R)

Tharollo:

3. Fumana phapang e ka bang teng mathokong ka bobeli a inductor.

Tse tsejoang:

R = 40 W

X _L = 150 W

XC = 120 _W

V = 100 Volt

Ho batloa: phapang e ka bang teng

Tharollo:

Kakaretso ea impedance Z ea potoloho:

Phapang e ka bang teng ea mahlakore ka bobeli a inductor:
