3. Tarisa dhayagiramu yedunhu reRLC inotevera!
Mwero wepamusoro wedunhu ndewekuti.. (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

Kukurukurirana

Zvinozivikanwa :
Mudziviriri (R) = 12 Ohm
Inductor (L) = 0,075 H
Capacitor (C) = 500 µF = 500 x 10^-6 F = 5 x 10^-4 Farad
Voltage (V) = V_o chivi ωt = V_o chivi 2πft = chivi 26 chivi 200t
Akabvunzwa : Kuwanda kwemagetsi edunhu
Jawab :

Kupindura kweInductive (X)_L) = ωL = (200)(0,075) = 15 Ohm
Kugadziriswa kwesimba (X)_C) = 1 / ωC = 1 / (200)(5 x 10^-4) = 1 / (1000 x 10^-4= 1 / 10^-1 = 10¹ = 10 Ohms   
Mudziviriri (R) = 12 Ohm
Kusapindirana (Z) :
Simba remazuva ano (I) :
I = V / Z = 26 Volts / 13 Ohms
I = 2 Volts/Ohm
I = 2 Amperes

4. Dunhu reRLC rakarongwa sezvakaratidzwa mumufananidzo uri pazasi. Girafu ye sine wave inobuda kana_L > X_C iri…

Kukurukurirana

Information :
X_L = inductive reactance kana inductor impedance
X_C = capacitive reactance kana capacitor impedance

Mu inductor, voltage yemagetsi (v) inotangira magetsi emagetsi (i) ne ¼ turn kana 90°.^o.
Mu capacitor, magetsi emagetsi (i) anotangira magetsi emagetsi (v) ne ¼ turn kana 90°.^o.

Kana X_L > X_C ipapo dunhu racho rinoita kuti pave ne inductive, saka girafu ye sine wave inobuda inoita semhinduro C apo voltage (v) iri pamberi pe current (i) ne ¼ turn kana 90°^o.

Mhinduro chaiyo ndiC.
