Me pēhea te whakamātautau i te whakamahana ngongo o te oumu he tikanga pai, ā, ko te whakamahinga o te whakamahana oumu te mea tino noa i roto i ngā taputapu e hiahia ana kia whakamahana. Heoi, ki te pakaru te ngongo whakamahana, ā, kāore e whakamahia, me aha tātou? Me pēhea tātou e whakatau ai mēnā he pai, he kino rānei te ngongo whakamahana?
1, ka taea te ine i te ātete mā te mita maha, he pai te iti o te ohms ki te tekau o te ohms, he kino te mano o te ohms, tae atu ki te teitei ake.
2. E ai ki te mana hoahoa o te ngaohiko me te whakamahana ngongo oumu, ka tatauhia te tātai ātete o te ngongo whakamahana penei i a R = (V x V)/P (ko R te ātete, ko V te ngaohiko, ko P te mana). He pai te hua mena he nui ake i te 0, he iti iho i te 1000.
3, nō reira, ina inehia mā te kōnae ohm (×10Ω) o te mita maha, ki te kore mutunga te pānui, ki te tata rānei ki te mutunga kore, he ara iahiko tuwhera. Ko ngā pānui e tohu ana he noa, kāore he kino.
4. Mēnā kāore te ngongo whakamahana oumu e whakakāhia ana, tirohia mēnā he pū kōhao, he trachoma, he ngatata, he pakū rānei kei te mata o te tinana o te ngongo. Mēnā kāore he pū kōhao, he trachoma, he ngatata, he pakū rānei, he pai noa iho.
Tikanga Whakatau: Mena he mārama ngā kōhao, he trachoma, he ngatata, he pahūtanga rānei kei runga i te mata o te whakamahana oumu kowiri tira, he tohu tēnei kua pakaru te ngongo whakamahana, ā, kāore e taea te whakamahi i te nuinga o te wā. Ina kore te uara ātete i inehia, he tohu anō hoki kāore e taea te whakamahi i te ngongo whakamahana; mena kei te ora tonu te mata, ā, kei roto te uara ātete i te awhe noa, me kimi ētahi atu take.
Mena kei te hiahia koe ki ā mātou hua, whakapā mai ki a mātou!
