Tuatahi, te awe o te kawe hiko ki te mita rere hikohiko
He taputapu ine te mita rere hiko-aukume e whakamahia ana mō te ine rere wai me te hau. Ko ngā mahi ine a ngā mita rere hiko-aukume he mea mō ngā wai, ngā hau rānei e kawe ana i te hiko. Mēnā he ngoikore te kawe hiko, ka ngāwari te horapa o te tohu ki te pokanoa, ka hua ake he hua ine hē. Nō reira, he mea tino nui hoki ngā whakaritenga kawe hiko o ngā mita rere hiko-aukume.
Tuarua, ko ngā whakaritenga kawe hiko o ngā mita rere hikohiko
I raro i ngā āhuatanga noa, me eke te kawe hiko o te mita rere hikohiko ki runga ake i te 0.1S/m. Mēnā ka eke te kawe hiko ki runga ake i te 0.1S/m, ka taea e te mita rere hikohiko te kite me te ine i te au me te papa aukume. Mēnā he iti iho te kawe hiko i te 0.1S/m, ka ngoikore te tohu putanga o te mita rere hikohiko, ka piki ake te hapa, ā, ka puta he āhuatanga nekeneke nui, ka pā tika ki te whakamahinga o te mita rere hikohiko.
3. Ngā whakaritenga kawe hiko i roto i ngā horopaki tono rerekē
He rerekē te kawe hiko o ngā wai me ngā hau rerekē, nō reira i ngā āhuatanga tono rerekē, he rerekē anō hoki ngā whakaritenga kawe hiko mō ngā mita rere hikohiko. Hei tauira, mō te paru, te penupenu, te waikawa waikawa, te wai moana me ētahi atu wai me nui ake te kawe hiko i te 0.1S/m; mō te hau, te hinu, te hau māori me ētahi atu hau me nui ake te kawe hiko i te 10^-6S/m. I ngā whakamahinga mahi, me whiriwhiri ngā hua mita rere hikohiko e tika ana kia rite ki ngā whakaritenga o ngā āhuatanga rerekē, ā, me whakarerekē te kawe hiko kia rite ki te hiahia.
Hei whakarāpopototanga, me eke te kawe hiko o te mita rere hikohiko ki te 0.1S/m te iti rawa, ā, i roto i ngā āhuatanga whakamahinga rerekē, he rerekē ngā whakaritenga mō te kawe hiko o te mita rere hikohiko. He mea nui te mārama ki te kawe hiko o te mita rere hikohiko mō te whakamahinga tika o te mita rere hikohiko.
