OHM's LAW - Nws yog dab tsi. Nws ua haujlwm li cas.

Tus kheej LEARNING AID rau cov neeg txaus siab thiab mob siab kawm. Tsuas yog nyeem cov nplooj ntawv hauv qab no nrog kev saib xyuas lossis hu rau lawv siv HELP ua haujlwm raws li kev ua haujlwm. A) Kawm cov xim xim rau cov neeg tawm tsam los ntawm kev xyaum. B) Kawm paub xam qhov tseem ceeb rau SERIES, PARALLEL, SERIES-PARALLEL circuits. Cov hluav taws xob tau pib tsim thiab tso tawm kom pom. Cov lus teb raug txheeb xyuas thiab daim npav qhab nia raug khaws cia. Xaiv ib qib ntawm qhov nyuaj: (E) asy, (D) ifficult, (E) xpert. Lub tshuab xam zauv thiab sau ntawv xav tau rau qib siab dua. Tsuas yog tus ntawv sau yuav ua rau qib (E) asy. TSEEM CEEB: Teb cov lus nug ntawm kev xav yuav ua rau tsis ua tiav thiab poob siab. Nyeem cov lus qhia uas ua ntej tus cursor nrog kev saib xyuas thiab teb zoo ua ntej yuav mus (nias ENTER). NCO NTSOOV: GIGO - Khib Nyiab Hauv, Khib Nyiab Tawm

Kauj Ruam 1: Cov Ntsiab Lus Ntawm Dab Tsi Muaj

HELP: Pib los ntawm kev nyeem tag nrho cov nplooj ntawv (5) hauv ntu (H) elp ntu. Cov nplooj ntawv tau nthuav tawm hauv qab no nrog rau qee cov ntawv nthuav dav.

Kauj Ruam 2: Xim Xim

Nplooj ntawv no piav qhia cov cai xim rau cov neeg tawm tsam.

Xaiv qhov kev ua haujlwm no thawj zaug thiab ua kom xis nyob nrog cov cai. Vim tias muaj qhov sib txawv ntawm cov xim ntawm cov lus sib txawv, cov ntawv luv (piv txwv li 'Viol' rau violet) ntawm cov xim npaj tau faib ua ntej ntawm tus cursor thaum twg los xij cov lus txhais xim raug hu rau. Ib txoj hlua ntawm cov xim tau tso rau ntawm sab xis sab xis ntawm tha screen txhua lub sijhawm. Nov yog kev tawm dag zog lom zem!

Kauj Ruam 3: Cov Cai Dav Dav - Kev Tiv Thaiv Network

Cov no yog cov kev cai dav dav rau nrhiav tag nrho cov resistans (Rt) ntawm kev tawm tsam network. Nco tseg: Rt = Tag nrho kev tiv thaiv, Rs = Series tsis kam (tiag tiag Rt rau SERIES network), Rp = Parallel tsis kam (tiag tiag Rt ntawm kev sib txuas network), Req = sib npaug tsis kam. Ntau nplooj ntawv no ob peb zaug yog tias tsim nyog lossis txog thaum koj tau yooj yim nrog cov lus siv.

Kauj Ruam 4: Cov Cai Dav Dav

Cov no yog cov kev cai dav dav rau kev ua ntu zus thiab rau cov kab sib txuas sib txuas. Ntau ntawm WIRES carying ELECRICITY, xav txog tias koj muaj Yeeb Nkab nqa dej. Kev Ntsuas Dej yog qhov sib piv rau VOLTAGE, RESISTANCE rau cov dej ntws (ntxhib nto rau qhov ua piv txwv) zoo ib yam rau RESISTANCE rau qhov hluav taws xob ntws, AMOUNT cov dej ntws hauv/tawm PIPE zoo ib yam rau CURRENT (AMPERES) uas muaj hauv qhov hluav taws xob hluav taws xob. Saib cov duab hauv qab no. Lub ntsiab lus ntawd tseem yog qhov kawg::: Tsuas muaj ib txoj hauv kev hla lub voj::: Lub voj yog zoo li daim duab z-e-r-o. SERIES cov kav dej tau txuas qhov kawg-rau-kawg. Yog tias muaj kev nyab xeeb tas mus li ntawm cov dej hauv cov yeeb nkab, koj tuaj yeem kos tib lub AMOUNT ntawm cov dej nyob rau lub sijhawm tsis muaj mater qhov twg koj kaw (lossis ntaus) lub yeeb nkab. AMOUNT = CURRENT = AMPERES: *** IN A SERIES CIRCUIT THE CURRENT IS THE SAME IN ALL PARTS ***. yeeb nkab. Lwm qhov twg tuaj yeem tiv taus los ntawm? *** IN A SERIES CIRCUIT Rt = R1+R2+…. Rx *** Tag nrho kev tiv thaiv sib npaug sib npaug ntawm txhua tus tib neeg kev tawm tsam. Pib los ntawm ib kis hauv SERIES lub voj, lub siab yuav poob hauv ntu txuas ntawm cov yeeb nkab vim tsis kam ntws. Qhov sib npaug ntawm txhua qhov poob hauv siab thoob plaws txhua ntu ntawm cov yeeb nkab hauv SERIES lub voj yog tib yam li qhov poob ntawm qhov siab ntawm qhov pib piont: *** Hauv Ib Lub Caij Nplooj Ntoos Zeeg, Lub VOLTAGE DROP yog sib npaug rau SUM ntawm VOLTAGE DROPES ACROSS EACH COMPONENT *** IN PARALLEL::: Siv cov yeeb nkab dej sib piv, xav txog cov kav dej txuas nrog ua ke hauv daim duab yim:::: Los ntawm ib qho pib qhov pib muaj ntau dua ib txoj hauv kev lossis ceg ntoo uas dej tuaj yeem ua tau ntws. Qhov zais cia rau kev daws teeb meem nrog cov kab hluav taws xob sib cais yog cais txhua BRANCH thiab siv cov kev cai SERIES uas tau piav qhia saum toj no txhawm rau nrhiav qhov tsis txaus ntseeg rau txhua tus BRANCH (Req1 thiab Req2 hauv qhov no). Qhov no muaj txiaj ntsig txo qhov kev sib tw mus rau ZOO TSHAJ PLAWS (Req1 thiab Req2) hauv SERIES. Raws li nrog cov kab hluav taws xob hauv SERIES, ZOO TSHAJ PLAWS yog qhov sib npaug ntawm tus kheej kev tawm tsam - Rpt = Req1+Req2 hauv qhov no. Kawm qhov piv txwv hauv Duab 5 nrog saib xyuas Thaum koj nkag siab qhov piv txwv no koj yuav muaj kev ntseeg siab thaum daws cov teeb meem zoo sib xws.

Kauj Ruam 5: Kev Tiv Thaiv Ib Leeg - Yuav Ua Li Cas

Kawm tus piv txwv hauv daim duab no kom txog thaum koj nkag siab zoo. Nco ntsoov dab tsi tau hais txog BRANCHES hauv kauj ruam 4. TSWV YIM: Txoj hauv kev nrawm los nrhiav qhov sib npaug ntawm ob qhov kev tawm tsam sib npaug yog faib lawv cov khoom los ntawm lawv cov lej: Rt = (R1xR2)/(R1+R2). Yog R1 = 20 thiab R2 = 30, ces Rt = 20x30/20+30 = 600/50 = 12 Nws ua raws li ntawd yog tias R1 = R2, ces Rt = ib nrab ntawm ib qho ntawm lawv. Yog R1 = 20 thiab R2 = 20, ces Rt = 20x20/20+20 = 400/40 = 10::: Hauv qhov piv txwv hauv qab no, xav txog 't' ua TOP, 'v' li VERTICAL, thiab 'b' li BOTTOM.::: BRANCH 3 muaj Rt3, Rv3, thiab Rb3 hauv SERIES. Yog li Rs3 = Rt3+Rv3+Rb3 = 30+40+50 = 120 los ntawm peb Txoj Cai Kev Cai. Tam sim no Rs3 nyob hauv PARALLEL nrog Rv2 thiab qhov sib npaug sib npaug, Req1, tau suav raws li tau piav qhia hauv qab TSWV YIM, saum toj no: Req1 = (Rs3xRv2)/(Rs3+Rv2) = (120x30)/(120+30) = 3600/150 = 24 Tam sim no BRANCH 3 muaj qhov sib npaug tiv taus ntawm 24::: BRANCH 2 muaj Rt2, Req1 thiab Rb2 hauv SERIES. Yog li Rs2 = Req1+Rt2+Rb2 = 24+40+20 = 84 los ntawm peb Txoj Cai Kev Cai. Tam sim no Rs2 nyob hauv PARALLEL nrog Rv1 thiab qhov sib npaug sib npaug, Req2, tau suav raws li tau piav qhia hauv TSWV YIM, saum toj no: Req2 = (Rs2xRv1)/(Rs2+Rv1) = (84x40)/(84+40) = 3360/124 = 27 Tam sim no BRANCH 2 muaj qhov sib npaug ntawm 27::: BRANCH 1 muaj Rt1, Req2 thiab Rb1 hauv SERIES. Yog li Req3, tam sim no Rt = Req2+Rt1+Rb1 = 27+10+50 = 87, ZOO TSHAJ PLAWS RESISTANCE ntawm Circuit VOILA!

Kauj Ruam 6: Cov ntsiab lus ntawm Cov Cai

Hauv qab no yog cov ntsiab lus ntawm cov cai ntawm OHM's LAW thiab ntau ntxiv.

Xav txog cov kav dej thiab dej hloov ntawm cov xov hlau thiab hluav taws xob yog tias koj xav tau.

Kauj Ruam 7: Cov Ntsiab Lus Ntawm Yam Koj Ua Tau

Koj tuaj yeem xaiv los ntawm 3 yam sib txawv ntawm kev tawm dag zog:

A - Xim xim B - Kev ntsuas: xaiv hom thiab DEVFICULTY LEVEL C - Tsim kom muaj kev tiv thaiv Circuit Court thiab ua qhov kev suav. Koj txoj haujlwm yuav raug txheeb xyuas. ADVICE: Nkag mus rau cov lus teb tsis raug yuav ua rau GIGO (Khib Nyiab Hauv, Khib Nyiab Tawm) Xyaum nrog cov teeb meem yooj yim ua ntej. Koj yuav tau txais kev ntseeg siab thiab kev txawj ntse, dua li mus rau cov teeb meem nyuaj dua. RUN R. EXE thiab tos rau qhov program kom thauj khoom thiab pib ua haujlwm. Tsis quav ntsej qhov chaw nyob, thiab lwm yam, ntawm nplooj ntawv npe.
