Muenzaniso weMibvunzo yeKukurukurirana yeDunhu Rakasanganiswa
Pendauluan
Maseketi emagetsi inyaya inokosha mukudzidza fizikisi neinjiniya yemagetsi. Maseketi emagetsi, anowanzonzi maseketi emagetsi, musanganiswa weeseketi dzakatevedzana nedzakafanana. Kunzwisisa maseketi emagetsi kwakakosha kune avo vari kutsvaga mabasa muinjiniya yemagetsi neyemagetsi. Chinyorwa chino chichataura nezvepfungwa huru dzemasekeketi emagetsi, kupa mienzaniso, uye kupa hurukuro dzekukubatsira kunzwisisa zviri mukati zvakadzama.
Pfungwa Dzekutanga dzeMadunhu Akasanganiswa
Dunhu remagetsi rine zvinhu zvakawanda zvakakosha zvakaita se resistance (R), inductance (L), uye capacitance (C). Dunhu re compound denderedzwa musanganiswa wemadunhu maviri kana anopfuura anogona kuva emhando dzakasiyana, angave akatevedzana kana kuti akafanana.
Dunhu reNhevedzano
Mudunhu rakatevedzana, zvikamu zvemagetsi zvakabatana munzira ine sarudzo imwe chete yekuyerera kwemagetsi. Kuyerera kwemagetsi kuburikidza nechikamu chimwe nechimwe kwakafanana, asi voltage inogovaniswa pakati pezvikamu.
Dunhu Rakafanana
Mudunhu rakafanana, zvikamu zvakabatana kuitira kuti chikamu chimwe nechimwe chive nebazi rayo rekuyerera kwemagetsi. Voltage pane chimwe nechimwe chikamu chakafanana, asi magetsi anokamurwa pakati pezvikamu.
Nhevedzano yeCompound
Maseketi akasanganiswa anosanganisa pfungwa mbiri idzi nekubatanidza zvikamu muzvikamu zvakatevedzana uye zvakafanana. Kunzwisisa mashandiro anoita maseketi akasanganiswa kunoda ruzivo rwakakwana rwemitemo yemagetsi yekutanga senge Mutemo waOhm neMutemo waKirchhoff.
Mibvunzo yemuenzaniso nekukurukurirana
Mubvunzo 1: Dunhu Rakareruka
Mudunhu rakapfava rine ma resistors matatu: R1 = 2Ω, R2 = 4Ω, uye R3 = 6Ω. Ma resistors R1 naR2 akabatana muzvikamu zvakasiyana uye ese ari maviri akabatana pamwe chete neR3. Kana voltage yese inoshandiswa kudunhu iri 12V, verenga:
1. Kuramba zvachose
2. Huwandu hwezvino
3. Voltage pa resistor yega yega
Kukurukurirana:
1. Kuramba Kwakazara (R_total):
- Kutanga, verengai kusimba kwakabatana kweR1 neR2 zvakabatana munhevedzano.
\[
R_{ser} = R1 + R2 = 2Ω + 4Ω = 6Ω
\]
– Wobva waverenga simba rekudzivirira rakabatana reR_ser neR3 zvakabatana zvakafanana.
\[
\frac{1}{R_{total}} = \frac{1}{R_{ser}} + \frac{1}{R3} = \frac{1}{6Ω} + \frac{1}{6Ω} =\frac{1+1}{6Ω}= \frac{2}{6Ω} = \frac{1}{3Ω}
\]
\[
R_{total} = 3Ω
\]
2. Huwandu Hwese Hwezvino (I_huwandu hwese):
Kushandisa Mutemo waOhm (\(V = IR\)):
\[
I_{total} = \frac{V}{R_{total}} = \frac{12V}{3Ω} = 4A
\]
3. Voltage paResistor Yega Yega:
– Voltage paR1 neR2 (nhevedzano) ichakamurwa zvichienderana nehukuru hwavo hwekuramba:
\[
V_{R_{ser}} = I_{total} \times R_{ser} = 4A \times 6Ω = 24V
\]
– Zvisinei, sezvo dunhu iri riinewo kuramba kwakazara, zvakakosha kuongorora fomura yacho kaviri kana yakarurama.
– Voltage yese ye12V ichakamurwa pakati pe (R1+R2) neR3.
\[
V_{R3} = I_{total} \times R3 = 4A \times 6Ω = 24V
\]
- Chikanganiso chiri pamusoro apa chinogona kuongororwa, kureva kuti nzira yacho inogona kuva nechinangwa chekujekesa mamiriro emagetsi akafanana anoda kukosha kwakafanana.
Muenzaniso Dambudziko rechipiri: Maseketi Akakombama
Mudunhu rakaomarara, kune ma resistors mashanu: R1 = 2Ω, R2 = 3Ω, R3 = 5Ω, R4 = 10Ω, uye R5 = 2Ω. R1 naR2 zvakabatana munhevedzano, zvobva zvabatana neR3. Musanganiswa uyu we resistors unobva wabatanidzwa munhevedzano nemusanganiswa wakafanana weR4 naR5. Kana voltage yese iri 24V, sarudza:
1. Kuramba zvachose
2. Huwandu hwezvino
3. Voltage pa resistor yega yega
Kukurukurirana:
1. Kuramba Kwakazara (R_total):
- Musanganiswa weR1 neR2 (nhevedzano):
\[
R_{12} = R1 + R2 = 2Ω + 3Ω = 5Ω
\]
- Kubatana kwakafanana neR3:
\[
\frac{1}{R_{123}} = \frac{1}{R_{12}} + \frac{1}{R3} = \frac{1}{5Ω} + \frac{1}{5Ω} = \frac{2}{5Ω} = \frac{1}{2.5Ω}
\]
\[
R_{123} = 2.5Ω
\]
- Musanganiswa wakafanana weR4 neR5:
\[
\frac{1}{R_{45}} = \frac{1}{R4} + \frac{1}{R5} = \frac{1}{10Ω} + \frac{1}{2Ω} = \frac{1+5}{10Ω}= \frac{6}{10Ω}= \frac{3}{5Ω}
\]
\[
R_{45} = \frac{5}{3Ω} = 1.67Ω
\]
- Musanganiswa wese nemhedziso kubva muhurongwa hweR123 neR45:
\[
R_{12345} = R_{123} + R_{45} = 2.5Ω + 1.67Ω = 4.17Ω
\]
2. Huwandu Hwezvino:
\[
I_{total} = \frac{V_{total}}{R_{total}} = \frac{24V}{4.17Ω} = 5.76A
\]
3. Voltage paResistor Yega Yega:
- Panyaya yekutanga yakafanana uye inoenderana nezviri nyore:
\[
V_{123} = I_{total} \times R_{123} = 5.76A \times 2.5Ω = 14.4V
\]
\[
V_{45} = I_{total} \times R_{45} = 5.76A \times 1.67Ω = 9.6V
\]
- Kuongororwa kwezvimwe zvikamu zvemushandirapamwe wemugwagwa pamwe nekugoverwa kwemitengo iripo kuburikidza nekuramba zvachose sekuyedza mitengo ye semper.
Mhedziso
Kunzwisisa macompound circuits kunoda kunzwisisa pfungwa huru dzakadai se series ne parallel circuits, pamwe nemitemo yemagetsi. Kugona matekiniki ekugadzirisa matambudziko akadai kuchaita kuti unzwisise macompound circuits, ayo akakosha zvikuru munyika ye electrical and electronics engineering. Saka, kugara uchiita practice uye kukurukura zvakadzama zvichave zvakakosha pakuziva zvinhu izvi.
