Ua nīnau ʻia: Ke kū'ē kū'ē (R)

Pane:

ʻO ke ʻano hoʻohālikelike impedance holoʻokoʻa no ke kaapuni:

ʻO ka pane pololei ʻo B.

2. E noʻonoʻo i ke kaapuni RLC moʻo ma lalo nei! ʻO ka ʻokoʻa hiki ma nā wēlau o ka inductor….

Ua nīnau ʻia: ʻOkoʻa hiki ma waena o nā wēlau o ka inductor

Pane:

ʻO ke ʻano hoʻohālikelike impedance holoʻokoʻa no ke kaapuni:

ʻO C ka pane pololei.

3. E nānā i ke kiʻikuhi kaapuni RLC ma lalo nei!
ʻO ke au kiʻekiʻe loa o ke kaapuni he .. (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

Ua ʻike ʻia :
Palekana (R) = 12 Ohm
ʻO ka mea hoʻokomo (L) = 0,075 H
Ka mea hoʻonui (C) = 500 µF = 500 x 10^-6 F = 5 x 10^-4 Loaʻa
Voltage (V) = V_o sin ωt = V_o sin 2πft = 26 sin 200t
Ua nīnau ʻia : Ka nui o ke au o ke kaapuni
Pane :

ʻO ke kū'ē hoʻokomo (X)_L) = ωL = (200)(0,075) = 15 Ohm
Ka hana hoʻonui capacitive (X_C) = 1 / ωC = 1 / (200)(5 x 10^-4) = 1 / (1000 x 10^-4) = 1 / 10^-1 = 10¹ = 10 Ohms   
Palekana (R) = 12 Ohm
Palekana (Z) :
Ka ikaika o kēia manawa (I) :
ʻO I = V / Z = 26 Volts / 13 Ohms
ʻO I = 2 Volts/Ohm
ʻO I = 2 Amperes
ʻO C ka pane pololei.

4. Ua hoʻonohonoho ʻia ke kaapuni RLC e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei. ʻO ka kiʻi sine wave i loaʻa inā_L > X_C ʻo ia…

Pahana

ʻIkepili:
X_L = ka reactance inductive a i ʻole ka impedance inductor
X_C = ka reactance capacitive a i ʻole ka impedance capacitor

I loko o kahi inductor, ʻoi aku ka nui o ke au uila (v) ma mua o ke au uila (i) ma ka ¼ huli a i ʻole 90°.^o.
I loko o kahi capacitor, ʻoi aku ke au uila (i) ma mua o ke au uila (v) ma ka ¼ turn a i ʻole 90°.^o.

Inā ʻo X_L > X_C a laila he inductive ke kaapuni, no laila ke ʻano o ka pakuhi nalu sine hopena e like me ka pane C kahi i mua ai ke au uila (v) ma mua o ke au (i) ma ka ¼ huli a i ʻole 90°^o.

ʻO C ka pane pololei.

5. E nānā i ke kiʻi ma lalo nei!

Ua hoʻonohonoho ʻia ke kaapuni RLC e like me ka mea i hōʻike ʻia ma luna. ʻO ka kiʻi nalu sine hopena inā_L > X_C ʻo ia…
