Hape ithute thepa e mabapi le khanyetso ea motlakase , mehlala ea mathata a khanyetso ea letoto , mehlala ea mathata a khanyetso e bapileng.
Mehlala e 2 ea Lipotso tsa Khanyetso ea Motlakase
1. Sesebelisoa sa motlakase se hokahantsoe le mohloli oa motlakase oa 30 Volt 'me se na le motlakase oa 2 Amperes. Fumana khanyetso ea motlakase ea sesebelisoa!
Puisano
Hoa tsebahala hore:
Motlakase oa motlakase (V) = Li-volt tse 30
Motlakase oa motlakase (I) = 2 Ampere
Potso: Khanyetso ea motlakase (R)
Karabo:
Foromo ea ho hanyetsa motlakase:
R = V / I
Tlhaloso: R = khanyetso ea motlakase, V = motlakase oa motlakase, I = motlakase oa motlakase.
R = 30 Volts / 2 Amps = 15 Volts/Amperes = 15 Ω (bala: Ohms).
2. Bala khanyetso ea motlakase ea li-conductor tse 'maloa tse bolelele ba mithara e le 1 le sebaka se tšekaletseng sa 1 x 10 -5 m2 . Khanyetso ea li-conductor e boletsoe tafoleng e ka tlase.
Puisano
Foromo ea ho hanyetsa motlakase:
Tlhaloso: R = khanyetso ea motlakase, ρ = khanyetso e itseng, l = bolelele ba mokhanni, A = sebaka se tšekaletseng sa mokhanni.
