Dzidzawo nezvenyaya yekudzivirira magetsi , mienzaniso yematambudziko ekudzivirira akatevedzana , mienzaniso yematambudziko ekudzivirira anoenderana.
Mienzaniso miviri yeMibvunzo yeKuramba Kwemagetsi
1. Mudziyo wemagetsi wakabatana nesimba remagetsi re30 Volt uye une simba remagetsi re2 Amperes. Sarudza kuti mudziyo wacho unodzivirira magetsi zvakadini!
Kukurukurirana
Zvinozivikanwa kuti:
Mhepo yemagetsi (V) = 30 Volts
Mwenje wemagetsi (I) = 2 Amperes
Mubvunzo: Kudzivirira magetsi (R)
Mhinduro:
Fomura yekudzivirira magetsi:
R = V / Ini
Tsananguro: R = kuramba magetsi, V = voltage yemagetsi, I = magetsi emagetsi.
R = 30 Volts / 2 Amps = 15 Volts/Amperes = 15 Ω (verenga: Ohms).
2. Verengai simba remagetsi remakondirakita akasiyana-siyana ane urefu hwemita imwe uye nzvimbo ine chikamu che1 x 10 -5 m2 . Simba remakondirakita rakataurwa mutafura iri pazasi.
Kukurukurirana
Fomura yekudzivirira magetsi:
Tsananguro: R = kuramba kwemagetsi, ρ = kuramba kwakananga, l = kureba kwemutyairi, A = nzvimbo yemutyairi.
