LEEM-25 Potentiometer Experiment
Ko nga tawhā hangarau matua
1. DC whakau i te mana hiko: 4.5V, e toru me te hawhe te whakaatu mamati, me te taputapu whakawhāiti nāianei;
2. Paerewa hiko hiko: 1.0186V, tika ± 0.01%, utu aunoa te pāmahana;
3. galvanometer Mamati: 5 × 10-4, 10-6, 10-8, 10-9A wha-tere te whakarite te tairongo;
4. Pouaka ātete: (0~10)×(1000+100+10+1)Ω, ±0.1%
5. E rua nga EMF hei ine, nama 1 pouaka pākahiko, me te pouaka whakawehe ngaohiko i roto.
6. Ko te anga o te potentiometer tekau ma tahi-waea he mea hanga ki te plexiglass, me te hanganga o roto me te rahi iti;
7. Ko ia waea parenga he rite ki te mita kotahi, a ko te uara parenga he 10Ω;
8. Tekau nga waea atete ka werohia ki runga i te rakau plexiglass, kua whakaritea ki roto i te pouaka maramara, ka honoa ki a raatau ano;
9. Ka werohia te waea whakaahuru ma tahi ki runga i te kopae parenga hurihuri, ka wehea te tauine ki nga wehenga 100.Ma te whakamahi i te vernier, ka taea te tika ki te 1mm;te tapeke ātete raupapa he 110Ω.
10. Ka taea te kowhiri i te potentiometer waea kotahi tekau ma tahi hei whakamatautau
