LEEM-25 Potentiometer Experiment

Cov txheej txheem tseem ceeb
1. DC ruaj khov fais fab mov: 4.5V, peb-thiab-ib-nrab digital zaub, nrog rau tam sim no txwv ntaus ntawv;
2. Lub zog hluav taws xob txheem: 1.0186V, qhov tseeb ± 0.01%, kev them nyiaj tsis siv neeg rau qhov kub tas li;
3. Digital galvanometer: 5 × 10-4, 10-6, 10-8, 10-9A plaub-ceev kho tau qhov rhiab heev;
4. Lub thawv tiv thaiv: (0 ~ 10) × (1000 + 100 + 10 + 1) Ω, ± 0.1%
5. Ob lub EMFs uas yuav tsum tau ntsuas, Lub thawv roj teeb No. 1, nrog rau lub thawv faib hluav taws xob sab hauv.
6. Lub plhaub ntawm kaum ib-hlau potentiometer yog ua los ntawm plexiglass, nrog rau cov qauv sab hauv thiab me me;
7. Txhua txoj hlau tsis kam yog sib npaug rau ib 'meter', thiab tus nqi tsis kam yog 10Ω;
8. Kaum txoj hlua tiv thaiv tau qhwv rau ntawm tus pas nrig plexiglass, teeb tsa rau hauv lub thawv pob tshab, thiab txuas ua ke ua ke;
9. Cov hlau tiv thaiv kaum ib yog qhwv rau ntawm lub disc tiv thaiv tig tau, thiab qhov ntsuas tau muab faib ua 100 qhov sib npaug. Siv lub vernier, nws tuaj yeem ua tau raws li 1 hli; tag nrho cov kev tiv thaiv series yog 110Ω.
10. Ib qho potentiometer kaum ib-xaim ib txwm tuaj yeem xaiv rau kev sim
