Mienzaniso mitatu yeMibvunzo yeMutemo weOhm
1. Zvichibva padata riri mutafura, kukosha kwekudzivirira magetsi ndeku….. Ko data riri mutafura rinotsanangura mutemo weOhm here?
Kukurukurirana
R = V / I = 2 volts / 4 Amps = 1/2 Ω
R = V / I = 4 volts / 8 Amps = 1/2 Ω
R = V / I = 3 volts / 6 Amps = 1/2 Ω
R = V / I = 5 volts / 10 Amps = 1/2 Ω
Zvinoenderana nemutemo waOhm, V/I haichinji. Saka zviri patafura iri pamusoro apa zvinotsanangura mutemo waOhm.
2. Mwenje uri muwaya yekufambisa magetsi i4 A. Kana musiyano uripo kumativi ese ari maviri uri 12 Volts, chii chinonzi resistance?
Kukurukurirana
R = V / I = 12 volts / 4 Amps = 3 Ω
3. Ko data riri patafura iri pazasi rinotsanangura mutemo weOhm here?
Kukurukurirana
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
Kukosha kweV/I hakusi kwekugara kwenguva dzose saka hakutsananguri mutemo weOhm. Mutemo weOhm unoshanda kana kukosha kweV/I kuri kwekugara kwenguva dzose.
