Azịza:

Usoro mgbochi mkpokọta maka sekit ahụ:

Azịza ziri ezi bụ C.

3. Lee eserese sekit RLC ndị a!
Oke ọkụ eletrik nke sekit ahụ bụ.. (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

Mkparịta ụka

A maara :
Nguzogide (R) = 12 Ohm
Inductor (L) = 0,075 H
Kapasitọ (C) = 500 µF = 500 x 10^-6 F = 5 x 10^-4 Farad
Voltaji (V) = V_o mmehie ωt = V_o mmehie 2πft = 26 mmehie 200t
A jụrụ : Oke ọkụ eletrik nke sekit ahụ
Jawab :

Mmeghachi omume inductive (X)_L) = ωL = (200)(0,075) = 15 Ohm
Mmeghachi omume ike (X)_C) = 1 / ωC = 1 / (200) (5 x 10^-4) = 1 / (1000 x 10^-4) = 1/10^-1 = 10¹ = 10   
Nguzogide (R) = 12 Ohm
Mgbochi (Z) :
Ike dị ugbu a (I) :
I = V / Z = 26 Volts / 13 Ohms
I = 2 Volts/Ohm
I = 2 Ampere
Azịza ziri ezi bụ C.

4. A haziri sekit RLC dịka egosiri na foto dị n'okpuru. Grafụ sine ebili mmiri nke sine na-apụta ma ọ bụrụ_L > X_C bụ…

Mkparịta ụka

Ozi:
X_L = mmeghachi omume inductive ma ọ bụ impedance inductor
X_C = mmeghachi omume capacitive ma ọ bụ impedance capacitor

N'ime inductor, voltaji eletriki (v) na-ebute ọkụ eletrik (i) ụzọ site na ntụgharị ¼ ma ọ bụ 90°.^o.
N'ime kapasitọ, ọkụ eletrik (i) na-ebute voltaji eletrik (v) ụzọ site na ntụgharị ¼ ma ọ bụ 90°.^o.

Ọ bụrụ na X_L > X_C mgbe ahụ sekit ahụ na-abanye n'ime ihe, ya mere eserese ebili mmiri sine nke a na-enweta dị ka azịza C ebe voltaji (v) dị n'ihu ugbu a (i) site na ntụgharị ¼ ma ọ bụ 90°^o.

Azịza ziri ezi bụ C.

5. Dị njikere!

A haziri sekit RLC dịka egosiri n'elu. Grafụ sine ebili mmiri nke na-apụta ma ọ bụrụ_L > X_C bụ…

Mkparịta ụka

Ozi:

X_L = mmeghachi omume inductive ma ọ bụ impedance nke inductor, X_C = mmeghachi omume capacitive ma ọ bụ impedance capacitor.

N'ime inductor, voltaji eletriki (V) na-ebute ọkụ eletrik (I) ụzọ site na ntụgharị ¼ ma ọ bụ 90°.^o.

N'ime kapasitọ, ọkụ eletrik (I) na-ebute voltaji eletrik (v) ụzọ site na ntụgharị ¼ ma ọ bụ 90°.^o.

Ọ bụrụ na X_L > X_C mgbe ahụ sekit ahụ na-abanye n'ime ihe, ya mere eserese ebili mmiri sine nke a na-enweta dị ka azịza C ebe voltaji (v) dị n'ihu ugbu a (i) site na ntụgharị ¼ ma ọ bụ 90°^o.

Azịza ziri ezi bụ C.

6. A haziri sekit RLC dịka egosiri na foto dị n'okpuru. Grafụ sine ebili mmiri sine a na-enweta ma ọ bụrụ_L > X_C bu...

Mkparịta ụka

Ozi:

X_L = mmeghachi omume inductive ma ọ bụ impedance nke inductor, X_C = mmeghachi omume capacitive ma ọ bụ impedance capacitor

N'ime inductor, voltaji eletriki (V) na-ebute ọkụ eletrik (I) ụzọ site na ntụgharị ¼ ma ọ bụ 90°.^o.

N'ime kapasitọ, ọkụ eletrik (I) na-ebute voltaji eletrik (v) ụzọ site na ntụgharị ¼ ma ọ bụ 90°.^o.

Ọ bụrụ na X_L > X_C mgbe ahụ sekit ahụ na-abanye n'ime ihe, ya mere eserese ebili mmiri sine nke a na-enweta dị ka azịza C ebe voltaji (v) tupu agba (i) ruo ¼ ntụgharị ma ọ bụ 90^o.

Azịza ziri ezi bụ C.
