Mienzaniso mitanhatu yeMibvunzo yeMutemo weOhm
Dzidzawo mienzaniso yemutemo weOhm pamwe nezvinyorwa zvemutemo weOhm .
1. Tafura yezviyero zvemusiyano unogona kuitika uye simba remagetsi
Zvichibva patafura, hukama huripo pakati paV, I, naR...
A. V yakakura, I yakakura uye R inoramba yakafanana.
B. Kukosha kweR kunoenderana neI neV
C. Kukosha kweR chibereko cheV naI.
D. Kukosha kwaI kwakaenzana naR uye kwakaenzana naV.
Kukurukurirana
Fomura yemutemo weOhm:
V = IR kana R = V / I
Kukosha kwekudzivirira kwemagetsi zvichibva padata riri patafura ndekwekuti:
R 1 = V / I = 1,50 / 0,08 = 18,75 Ohms
R 2 = V / I = 2,80 / 1,50 = 2,87 Ohms
R 3 = V / I = 3,99 / 2,10 = 1,9 Ohms
Zvichibva patafura, hukama huripo pakati paV, I naR ndehwekuti kukosha kwaR kwakaenzana zvakanyanya naV naI. Izvi zvinoreva kuti V naI vakakura, R mudiki.
R haisi nguva dzose, saka data riri patafura iri pamusoro haritsananguri mutemo weOhm asi kuramba kwemagetsi. Mutemo weOhm unoshanda chete kana R iri nguva dzose.
Hapana mhinduro chaiyo.
2. Kushandisa waya yekufambisa magetsi yakareba zvakanyanya mudunhu kunoderedza magetsi. Izvi zvinokonzerwa ne...
A. Kuramba kunova kudiki
B. zvipingamupinyi zvinokura
C. voltage inokura
D. voltage inova diki
Kukurukurirana
Mhinduro chaiyo ndeiyi B.
3. Ndeipi girafu inoratidza hukama huripo pakati pemusiyano unokwanisa kuitika nemagetsi?
Kukurukurirana
Hukama huripo pakati pemusiyano ungangodaro uripo nemagetsi anowanikwa hunoratidzwa negirafu iri mumhinduro A.
4. Tarisa tafura inotevera yemhedzisiro yekuyedza. Zvichibva padata riri pamusoro, zvinogona kugumiswa kuti simba razvino...
A. inoenderana nemagetsi
B. zvinoenderana nevoltage
C. yakaenzana nevoltage
D. haina kukanganiswa nemagetsi
Kukurukurirana
Zvichibva padata riri patafura, kana voltage yakakwira, magetsi anowedzera. Saka, zvinogona kugumiswa kuti magetsi anoenderana zvakananga nemagetsi.
Mhinduro chaiyo ndeiyi B.
5. Mudziyo une resistance ye150 Ohm uye magetsi emagetsi e2A anopfuura nepakati pawo, saka musiyano ungangovepo ndewekuti...
A. 3,0 Volts
B. 7,5 Mavolts
C. 75 Volts
D. 300 Mavolts
Kukurukurirana
Zvinozivikanwa kuti:
Kuramba (R) = 150 Ohm
Mwenje wemagetsi (I) = 2 Amperes
Mubvunzo: Musiyano unogoneka kana voltage yemagetsi (V)
Mhinduro:
Fomura inotaura hukama huripo pakati pemagetsi, magetsi emagetsi uye kuramba kwemagetsi:
V = IR
Information :
V = magetsi emagetsi, I = magetsi emagetsi, R = kudzivirira magetsi
Musiyano ungangovapo kana voltage yemagetsi:
V = IR = (2 Ampere)(150 Ohm) = 300 Volts
Mhinduro chaiyo ndiD.
6. Mwenje uri muwaya yekudzivirira i4 A. Kana mativi ese ari maviri akapihwa mukana we12 Volts. Zvipingamupinyi zvingani?
A. 2 ohms
B. 3 ohms
C. 4 ohms
D. 5 ohms
Kukurukurirana
Zvinozivikanwa kuti:
Mwenje wemagetsi (I) = 4 Amperes
Mhepo yemagetsi (V) = 12 Volts
Mubvunzo: Kudzivirira magetsi (R)
Mhinduro:
Fomura inotaura hukama huripo pakati pemagetsi emagetsi, magetsi emagetsi uye kuramba kwemagetsi:
V = IR
Kudzivirira magetsi:
R = V / I = 12 Volts / 4 Amps = 3 Ohms
Mhinduro chaiyo ndeiyi B.
