Yuav ua li cas yog lub sinusoidal tam sim no

Lub fact tias ib tug sinusoidal alternating tam sim no ntws nyob rau hauv lub conductors ntawm tsev neeg thaiv, hnov txhua yam. Tab sis rau ib tug neeg txawv txawv nrog hluav taws xob engineering, cov nqe lus "sine" thiab, tshwj xeeb tshaj yog, "nce mus nce los", tsis muaj dab tsi yog hais tias. Nyob rau hauv daim ntawv no, peb yuav ua tiag muab ib tug tswv yim ntawm nws, ib qho yooj yim to taub rau txhua leej txhua tus.

Ua ntej ntawm tag nrho cov, koj yuav tsum txiav txim seb qhov kev txiav txim hais tias xws li hluav taws xob tam sim no. Raws li tam sim no piav qhia tam sim no - yog hais zog ntawm elementary hais muaj ib tug saib xyuas ntawm zoo los tsis zoo kos npe rau. Feem ntau, tus hais ntawm lub electrons to taub, tiam sis qhov no yog tsis muaj tseeb. Atom uas tau poob electrons vim protons tam sim no nyob rau hauv lub nucleus acquires ib tug zoo xwb, ua ion. EMF tsis yog lub electron tab sis kuj mus rau nws. Suffice nws rov qab hais tias, nyob rau hauv cov lus teb rau qhov zoo coj ntawm qhov tam sim no lub zog tau txais los ntawm ntxiv mus rho tawm, txawm hais tias nyob rau hauv kev muaj tiag, cov tsis zoo them hais tsiv mus nyob rau kev coj rov qab.

Qhov twg yog cov hais? Sawv cev neeg xyuas pib qauv: crystal lattice nrog atoms nyob rau hauv cov ntshav. Txhua atom yuav roughly piav raws li ib tug tej yam me me hnub ci system. Nyob rau hauv lub center ntawm ib tug loj heev cov tub ntxhais uas muaj protons thiab neutrons, thiab cov electrons tsiv mus nyob rau orbits nyob ib ncig ntawm nws.

Charge ntawm lub proton yog zoo thiab tsis zoo electrons, yog li ntawd lawv nrog attracted. Cov los ze zog mus rau lub keeb, lub zog sis. Yuav kom tam sim no arisen los ntawm qhov yuav tsum tau rau free atoms ntawm cov electrons thiab ua rau lawv tsiv mus nyob rau lub yam kev taw qhia. Lub generators no ua hauj lwm ntse nqa tawm los ntawm ib tug rotating magnetic teb. Nws yog qhia uas ploj lawm lub zog electrons nyob rau hauv tus txheej orbits, tso lawv. Ntawm cov hoob kawm, muaj yog tsis muaj direct tsheb. Nws yog ib qho kev pauv ntawm cov hais ntawm qhov ze atoms.

Qhov twg puas lub npe "sinusoidal tam sim no"? Yog vim li cas rau qhov no ntau lawm txoj kev. Peb sawv cev rau ob opposite tug ntawm cov hlau nplaum, thiab nruab nrab ntawm cov kab ntawm daim teb lub zog. Peb muab lub thav duab ntawm tus neeg xyuas pib nyob rau hauv daim teb no. Nws xaus yog kev cob cog rua rau ib tug load, txoj kev ua ib lub voj (Circuit Court). Rotating bezel. Thaum lub caij thaum nws nyob thaum uas tig mus rau qhov chaw ntawm cov hlau nplaum, tsis muaj tam sim no vim hais tias muaj yog tsis muaj kev tshuam nrog kab ntawm nro (ob tog ntawm tus ncej yog dej ntws yaug). Ntawm no nws yog me ntsis muab, cov kab ntawm cov magnetic teb hla tus neeg xyuas pib, tso electrons thiab tam sim no tshwm sim.

Nyob rau tib lub sij hawm rau lwm sab ntawm tus ncej thiab traverses lub teb, tab sis nyob rau sab nraud. Cov nqi siab tshaj plaws tam sim no - nrog ntsug tso kawm. Sinusoidal tam sim no - yog ib tug graphical sawv cev ntawm tus txheej txheem no. Yog tsis muaj nws tsis yooj yim rau to taub lub lag luam ntawm hluav taws xob khoom siv. Teeb qhia sinusoidal tam sim no nruab nrab yog cov Cartesian tswj nyob rau hauv lub dav hlau. Ntsug tam sim no axis yog ncua, thiab cov kab rov tav - lub sij hawm. Vim hais tias thaum lub sij hawm kev sib hloov ncej kaw qhov tseem ceeb yog tsis tseg pheej rov qab ua, yog generated sinusoidal tam sim no ua nyob rau hauv cov kev taw qhia thiab qhov ntau. Strung zoo li ib tug sine yoj nyob rau hauv lub sij hawm axis, txij thaum lub ib feem nyob saum toj no lub axis ntawm yoj (ib tug zoo kos npe rau), thiab lub qis ib feem (tsis zoo). Qhov siab tshaj plaws taw tes ntawm cov tsis sib haum mus rau txoj hauj lwm ncej thaum uas tig mus rau kab ntawm lub teb siv, thiab cov kev tshuam ntawm lub sij hawm axis (tam sim no yog zero) - perpendicular.

Hluav taws xob cov Circuit Court sinusoidal tam sim no feem ntau lug, raws li qhov no hom ntawm lub hwj chim heev tsuas hloov dua siab tshiab los ntawm transformers thiab lwm yam hluav taws xob Circuit Court hais, uas kis tau tus mob tshaj loj mus, thiab yuav tsum tau tes taws los piav. Dhau li ntawd, lub cim hauv paus ntsiab lus nws yuav lub creation ntawm ib tug sinusoidal tam sim no.
