3 Ngā Tauira o ngā Pātai Ture a Ohm
1. I runga i ngā raraunga o te ripanga, ko te uara o te ātete hiko ko... Kei te whakaahuahia e ngā raraunga o te ripanga te ture a Ohm?
Kōrero
R = V / I = 2 volt / 4 Ampere = 1/2 Ω
R = V / I = 4 ngaohiko / 8 Amps = 1/2 Ω
R = V / I = 3 ngaohiko / 6 Amps = 1/2 Ω
R = V / I = 5 ngaohiko / 10 Amps = 1/2 Ω
E ai ki te ture a Ohm, he pumau a V/I. Nō reira, e whakamārama ana ngā ihirangi o te ripanga i runga ake nei i te ture a Ohm.
2. Ko te iahiko i roto i tētahi waea kawe hiko he 4 A. Mena he 12 Volts te rerekētanga pūmanawa i ngā pito e rua, he aha te ātete?
Kōrero
R = V / I = 12 volts / 4 Amps = 3 Ω
3. E whakaahua ana ngā raraunga o te ripanga i raro nei i te ture a Ohm?
Kōrero
Ko te uara ātete hiko i runga i ngā raraunga o te ripanga ko:
R1 = V / I = 1,50 / 0,08 = 18,75 Ōhm
R2 = V / I = 2,80 / 1,50 = 2,87 Ōhm
R3 = V / I = 3,99 / 2,10 = 1,9 Ōhm
Kāore te uara V/I i te pumau, nō reira kāore e whakaahua i te ture a Ohm. Ka pā te ture a Ohm mēnā he pumau te uara V/I.
