3. Yang'anani chithunzi chotsatira cha RLC circuit!
Mphamvu yayikulu kwambiri ya dera ndi.. (1 µF = 10-6 F)
A. 1,3 A
B. 1,5 A
C. 2,0 A
D. 2,4 A
E. 2√2 A
Zokambirana
Ndizodziwika kuti :
Wotsutsa (R) = 12 Ohm
Inductor (L) = 0,075 H
Chojambulira (C) = 500 µF = 500 x 10-6 F = 5 x 10-4 Farad
Voliyumu (V) = Vo tchimo ωt = Vo tchimo 2πft = 26 tchimo 200t
Anafunsa : Mphamvu yayikulu ya dera
Yankhani :
Kuyankha koyambitsa (X)L) = ωL = (200)(0,075) = 15 Ohm
Kuyankha kwamphamvu (X)C) = 1 / ωC = 1 / (200) (5 x 10-4) = 1 / (1000 x 10-4) = 1/10-1 = 101 = 10 Ohms
Wotsutsa (R) = 12 Ohm
Kusakhazikika (Z) :
Mphamvu yamagetsi (I) :
I = V / Z = 26 Volts / 13 Ohms
I = 2 Volts/Ohm
I = 2 Ampere
Yankho lolondola ndi C.
4. Dongosolo la RLC lakonzedwa monga momwe zasonyezedwera pachithunzi chili pansipa. Chithunzi cha sine wave chomwe chikubwera ngatiL > XC ndi…
Zokambirana
Zambiri:
XL = reaction yoyambitsa kapena impedance ya inductor
XC = capacitive reactance kapena capacitor impedance
Mu inductor, magetsi amagetsi (v) amatsogolera magetsi amagetsi (i) ndi ¼ turn kapena 90°.o.
Mu capacitor, mphamvu yamagetsi (i) imayamba kutsogolo kwa mphamvu yamagetsi (v) ndi ¼ turn kapena 90°.o.
Ngati XL > XC ndiye kuti derali ndi lothandizira, motero graph ya sine wave yomwe ikubwera imawoneka ngati yankho C pomwe voltage (v) ili patsogolo pa current (i) ndi ¼ turn kapena 90°o.
Yankho lolondola ndi C.
5. Dziwani zambiri!
Dongosolo la RLC lakonzedwa monga momwe zasonyezedwera pamwambapa. Chithunzi cha sine wave chomwe chimachokeraL > XC ndi…
Zokambirana
Zambiri:
XL = reaction yoyambitsa kapena impedance ya inductor, XC = capacitive reactance kapena capacitor impedance.
Mu inductor, magetsi (V) amatsogolera magetsi (I) ndi ¼ turn kapena 90°.o.
Mu capacitor, mphamvu yamagetsi (I) imayamba kutsogolo kwa mphamvu yamagetsi (v) ndi ¼ turn kapena 90°.o.
Ngati XL > XC ndiye kuti derali ndi lothandizira, motero graph ya sine wave yomwe ikubwera imawoneka ngati yankho C pomwe voltage (v) ili patsogolo pa current (i) ndi ¼ turn kapena 90°o.
Yankho lolondola ndi C.
6. Dongosolo la RLC lakonzedwa monga momwe chithunzi chili pansipa chikusonyezera. Chithunzi cha sine wave chomwe chikubwera ngatiL > XC ndi...
Zokambirana
Zambiri:
XL = reaction yoyambitsa kapena impedance ya inductor, XC = capacitive reactance kapena capacitor impedance
Mu inductor, magetsi (V) amatsogolera magetsi (I) ndi ¼ turn kapena 90°.o.
Mu capacitor, mphamvu yamagetsi (I) imayamba kutsogolo kwa mphamvu yamagetsi (v) ndi ¼ turn kapena 90°.o.
Ngati XL > XC ndiye kuti derali ndi loyambitsa, chifukwa chake graph ya sine wave yomwe ikubwera imawoneka ngati yankho C pomwe tegangan (v) kutsogola aurus (i) mpaka ¼ kutembenuka kapena 90o.
Yankho lolondola ndi C.
