LEEM-2 Hangaia he Ammeter me te Voltmeter
Ko te miihini tohu DC me te voltmeter ka tukuna mai i te mahunga mita. Ko te upoko mita he galvanometer magnetoelectric te tikanga, ka taea noa e te wa o te micro ampere te taumata milliampere ranei te whakawhiti. Te tikanga, ka taea te mehua iti noa nei me te hiko. Hei whakamahi whaihua, me whakarereke kia nui ake ai tana whanganga mena ka taea te mehua hiko nui, hiko ranei. Ko te mita kua whakarereke kia whakamaherehia me te mita paerewa me te whakatau i te taumata tika. Ko tenei taputapu e whakarato ana i te katoa o nga taputapu whakamatautau mo te whakakii i te miihini iti ki te milliammeter voltmeter ranei. He whai kiko nga kaupapa whakamatautau, he maama te kaupapa, he pumau me te pono, a he whaitake te hoahoa hanga. Ka taea te whakamahi mo nga akonga o waenganui o te kura 'whakamatau whakarahinga ahupūngao kohinga ranei o te kaareti ahupūngao me te whakamatau hoahoa.
Nga Mahi
1. Kia maarama ki te hanganga taketake me te whakamahinga o te miihini microamp;
2. Akohia me pehea te whakawhnui i te whanganga inenga o te galvanometer me te maarama ki te kaupapa o te hanga i te mita whanui;
3. Akohia te tikanga whakatika mo te mita hiko.
