Ko nga pātai e pā ana
He aha te ture a Ohm?
E kī ana te ture a Ohm ko te auau o te auau puta noa i tētahi kaiārahi e ōrite ana ki te voltage i runga i a ia: V = I × R. Ka whakahōu anō, I = V / R me R = V / I.
He pēhea te kimi i te hiko hiko mai i te ture a Ohm?
Ko te hiko he voltage wā o te auau, P = V × I. Mā te whakamahi i te ture a Ohm ka taea hoki e koe te tuhituhi hei P = I² × R, P = V² / R rānei — e toru katoa e hoatu ana i ngā watts ōrite.
He uara e rua e tāuru ana au?
Ka kōwhiria te nui e ngaro ana ki roto i "Hoatu mō", kātahi ka tāuru i tētahi o ngā rua o ētahi atu e toru. Hei kimi i te ārai ka taea e koe te whakarato i te voltage me te rerenga, te hiko rānei me te rerenga.
Ka taea e au te whakamahi hiko i te wāhi o te whakarerekētanga, te rerenga rānei hei tāuru?
Hei. Mā te āpure hiko hōhonu e taea ai e koe te whakaoti mai i te hiko me tētahi atu nui — hei tauira, he utu 24 W i te 2 A e hoki ana ki te 12 V me te 6 Ω, mā te whakamahi i te V = P / I me te R = P / I².
He mahi te ture a Ohm mō ngā huringa AC?
E pā ana ki te wāhanga ārai o te arawhiti AC. Mō ngā arawhiti me ngā pūkōrero, ngā pūkōrero rānei e whakakapi ana koe i te ārai ki te ārai, ā, ka whiwhi te hiko i tētahi āhuatanga hiko, engari he ārai noa iho te V = I × R i ia wā.
He aha te wera i te mātau kaitautoko - he nui te hiko e whakawāteatia ai?
Ka huri te kaiārahi i te pūngao hiko ki te wera i P = I2 × R watts. Ko te kaiārahi 6 Ω e mau ana i te 2 A e whakawātea ana i te 4 × 6 = 24 W, nō reira e hiahiatia ana he mana nui ake i runga ake i tērā. Ko te whakaiti i te wattage te take noa iho o ngā kaiārahi whakawhāiti, whakawātea rānei.
Ka whakahaeretia e tēnei ngā wāhanga kāore i te paerangi pēnei i ngā pūrere, i ngā LED rānei?
Kāore. E whakaaro ana te ture a Ohm ki tētahi ārai pūmau, nō reira kāore e tauira ana i ngā kaiataata, LEDs, ngā pūrere rānei e tipu ana i te paerangi me te pūngao. Mō tētahi LED ka whakarārangitia e koe tētahi rārangi ārai mai i te pūngao whakarato i te pūngao LED ki mua.
