Muenzaniso weMibvunzo Inotaura NezveMaseketi Emagetsi
Maseketi emagetsi inyaya inokosha mufizikisi neinjiniya yemagetsi. Kunzwisisa mashandiro anoita maseti uye maitiro ekuverenga kukosha kwakakosha kune chero munhu anofarira engineering yemagetsi kana kushanda nemidziyo yemagetsi. Chinyorwa chino chichataura nezvemienzaniso yakati wandei yematambudziko eseketi emagetsi uye tsananguro dzawo senzira yekureva vadzidzi nenyanzvi vari kutsvaga kudzamisa ruzivo rwavo.
Nhanganyaya kuMasekete Emagetsi
Kazhinji, dunhu remagetsi rine zvikamu zvakati wandei zvekutanga zvakaita sema resistors, ma capacitor, ma inductors, uye ma voltage kana ma current sources. Zvikamu izvi zvakabatana muma configurations chaiwo kuti zviite mabasa chaiwo, akadai sekusefa ma signals kana kuwedzera kana kuderedza voltage. Mukuongorora dunhu, mitemo yeOhm neKirchhoff inowanzo shandiswa kuverenga current ne voltage mudunhu.
Muenzaniso Dambudziko 1: Dunhu Rakatsetseka Rakareruka
Mubvunzo:
Zvichienderana nedunhu rakatevedzana rine ma resistors matatu \( R1 = 2 \Omega \), \( R2 = 3 \Omega \), uye \( R3 = 5 \Omega \) akabatana nesosi yevoltage \( V = 10 V \). Verengai current inoyerera mudunhu uye voltage inodarika resistors imwe neimwe.
Kukurukurirana:
1. Tsvaga Kuramba Kwakazara:
Muchikamu cheseti, kupikisa kwese ndiko huwandu hwezvirambidzo zvese zvega zvega.
\[
R_{\text{total}} = R1 + R2 + R3 = 2 \Omega + 3 \Omega + 5 \Omega = 10 \Omega
\]
2. Tsvaga Mvura Inoyerera:
Zvinoenderana nemutemo weOhm, magetsi anogona kuverengerwa seizvi:
\[
I = \frac{V}{R_{\text{total}}} = \frac{10 V}{10 \Omega} = 1 A
\]
3. Tsvaga Voltage paResistor Yega Yega:
Voltage inodarika resistor yega yega inoverengwa seizvi:
\[
V_{R1} = I \times R1 = 1 A \times 2 \Omega = 2 V
\]
\[
V_{R2} = I \times R2 = 1 A \times 3 \Omega = 3 V
\]
\[
V_{R3} = I \times R3 = 1 A \times 5 \Omega = 5 V
\]
Saka, magetsi ari kuyerera mudunhu iri i1 A, uye voltage iri pamusoro pe resistor yega yega i2 V, 3 V, uye 5 V, zvichiteerana.
Muenzaniso Mubvunzo 2: Simple Parallel Circuit
Mubvunzo:
Tichitarisa circuit yakafanana ine ma resistors matatu \( R1 = 6 \Omega \), \( R2 = 3 \Omega \), uye \( R3 = 2 \Omega \) akabatana ne voltage source \( V = 12 V \). Verenga magetsi kuburikidza ne resistor yega yega.
Kukurukurirana:
1. Kushanda Kwemagetsi MuResistor Yega Yega:
Mudunhu rakafanana, voltage inodarika resistor yega yega yakafanana uye yakaenzana nevoltage inobva kwairi. Nokudaro, current inodarika resistor yega yega inoverengwa uchishandisa mutemo weOhm.
\[
I_{R1} = \frac{V}{R1} = \frac{12 V}{6 \Omega} = 2 A
\]
\[
I_{R2} = \frac{V}{R2} = \frac{12 V}{3 \Omega} = 4 A
\]
\[
I_{R3} = \frac{V}{R3} = \frac{12 V}{2 \Omega} = 6 A
\]
Saka, simba remagetsi rinobva kune resistor yega yega 2 A, 4 A, uye 6 A zvichiteerana.
Muenzaniso Mubvunzo 3: Musanganiswa weSeti neParallel Circuits
Mubvunzo:
Zvichienderana nedunhu rine musanganiswa we \( R1 = 4 \Omega \), \( R2 = 2 \Omega \), uye \( R3 = 3 \Omega \). \( R2 \) uye \( R3 \) zvakabatana zvakafanana, zvobva zvabatanidzwa mumutsara ne \( R1 \) uye sosi yemagetsi \( V = 15 V \). Verenga magetsi nemagetsi pane resistor yega yega.
Kukurukurirana:
1. Tsvaga kuramba kwakaenzana kwe \( R2 \) uye \( R3 \):
\[
\frac{1}{R_{\text{parallel}}} = \frac{1}{R2} + \frac{1}{R3} = \frac{1}{2 \Omega} + \frac{1}{3 \Omega} = \frac{3 + 2}{6} = \frac{5}{6 \Omega}
\]
\[
R_{\text{parallel}} = \frac{6}{5} \Omega = 1,2 \Omega
\]
2. Kuramba Kwakazara:
\[
R_{\text{total}} = R1 + R_{\text{parallel}} = 4 \Omega + 1,2 \Omega = 5,2 \Omega
\]
3. Huwandu Hwezvino:
\[
I_{\text{total}} = \frac{V}{R_{\text{total}}} = \frac{15 V}{5,2 \Omega} \approx 2,88 A
\]
4. Voltage pa \( R1 \):
\[
V_{R1} = I_{\text{total}} \times R1 = 2,88 A \times 4 \Omega \approx 11,52 V
\]
5. Voltage pa \( R2 \) uye \( R3 \):
Sezvo \( R2 \) uye \( R3 \) zviri zvakafanana, ma voltage akafanana:
\[
V_{\text{parallel}} = V – V_{R1} = 15 V – 11,52 V \inenge 3,48 V
\]
6. Tsvaga magetsi ari mu \( R2 \) uye \( R3 \):
\[
I_{R2} = \frac{V_{\text{parallel}}}{R2} = \frac{3,48 V}{2 \Omega} \approx 1,74 A
\]
\[
I_{R3} = \frac{V_{\text{parallel}}}{R3} = \frac{3,48 V}{3 \Omega} \approx 1,16 A
\]
Saka, magetsi ari kuyerera mudunhu iri anenge 2,88 A. Voltage iri kuyambuka \(\R1 \) inenge 11,52 V, uye magetsi ari kuyambuka \(\R2 \) uye \(R3 \) anenge 3,48 V. Marara ari kuyambuka \(\R2 \) i1,74 A uye kuyambuka \(\R3 \) i1,16 A.
