Kodi kupeza mphamvu munyengo zosiyanasiyana?

Mu moyo, nthawi zina pamakhala zinthu pamene pakufunikira vuto kugwirizana ndi mmene tingapezere mphamvu, ndiye kufunika kugwirizana ndi magulu a ntchito ndi nthawi. Cha pa thupi ndi zofunika chifukwa zimathandiza kudziwa mfundo zambiri. Mwachitsanzo, zingakhale zovuta kuwerengera nthawi imene lidzakhala wakewo anakonzeratu. Iye anafotokoza, ndi tionetsa, kumene, ntchitoyo osiyanasiyana injini. Pamaziko a mtengo uwu akhoza mtima, mwachitsanzo, mafuta. Ndiko kuti, ndikofunika, onse sayansi ndi chuma. Choncho, chigamulocho a zokhudza mmene tingapezere mphamvu, ali wamkulu wothandiza ndi othandiza tanthauzo.

mayunitsi

Conventionally, mphamvu wagawo angathe kugawidwa zokhudza zonse ndipo sanali zokhudza zonse. Mbali yoyamba, izo Watts (W kapena W) ndi mndandanda wa multiples ndi submultiples, mayina a amene anapanga ndi kuwonjezera manambala oyambirira kuti maziko pamwamba. Mwachitsanzo, kilowatts - chikwi chimodzi Watts. Pa mlingo thupi, gulu ili amadziwika ntchito kuti chichitidwe pa imeneyi nthawi. zotchuka kwambiri otchedwa "ndiyamphamvu" mwa mayunitsi sanali dongosolo. Ichi ndi chifukwa mphamvu ya ambiri a mkati injini kuyaka wa lero chimaonekera mu mayunitsi. Ubale zotsatirazi pakati pawo - mmodzi ndiyamphamvu ndi 735 Watt ndi theka. Tika anaganiza mayunitsi mu amene anayesa chizindikiro thupi, kuyankha funso pa za mmene tingapezere mphamvu mu sayansi ndi zamagetsi.

sayansi

Mphamvu mu sayansi n'zogwirizana ndi chizindikiro china chofunika - ntchito. Monga chizindikiro zofunika akutumikira nthawi. Mwaichi, mphamvu zingadziŵike mwa ntchito zimene zachitika kwa nyengo zina za nthawi. Choncho chilinganizo cha kuwerengetsa mphamvu ndi motere: N = A / T. Mu dongosolo ili, izi kalembedwe: N - mayunitsi mphamvu mu dongosolo, A - ntchito, amayezedwa joules, T - nthawi masekondi. Choncho, amasonyeza chofunika kuchuluka kwa ntchito, ndipo N limasonyeza kuti gawo la iyo, kuchitidwa chiweruzo, kuti nthawi izo pa imeneyi T.

zamagetsi

Okonza magetsi, mosiyana ndi sayansi, chirichonse chiri chophweka kwambiri. Onse mu chiphunzitso ndi kuchita. Theoretically, ndi chizindikiro chomwecho anatsimikiza ndi mankhwala a mfundo zenizeni za panopa ndi voteji. Ndiko kuti, mfundo ndi P = U * I. kumene P - ndi mphamvu zonse za wattage chomwecho. U - voteji, amayezedwa volts, ndipo ine - ziliri pa amperes. Ndondomeko ndi chilengedwe, mawu wapatsidwa chomveka kwa onse DC ndi AC. Ndi inu mosavuta kudziwa kuchuluka kwa mphamvu chipangizo china chilichonse. Komanso, mu kuchita, chipangizo mmodzi yekha - mita. Choyamba, miyezo kufanana chimatanthauza voteji, ndiyeno siriyo - panopa. Nthawi zambiri, njira imeneyi mukhoza kupeza yankho la funso bwanji kupeza mphamvu ya injini. Kapenanso, kuwerenga mungathe kuti ntchito wattmeter. Koma izi zida chingwe ndi odula kwambiri, chifukwa ichi, si ili ponseponse. Koma multimeters kale kukhala mbali ya moyo wathu tsiku ndi tsiku ayamba ntchito. Iwo ndi ntchito zake zosiyanasiyana chachikulu chimene chimasiyanitsa iwo ndi zipangizo zina, amene kwambiri apadera.

chidule

Nkhaniyi kutithandiza kuyankha funso mmene tingapezere mphamvu mu sayansi ndi zamagetsi. Kunena zoona, mu zamagetsi ya Izi amaika sizivuta kudziwa. Koma ngati inu mukufuna pogwiritsa ntchito njira zamakono luso angathetse ntchito iliyonse, mu chirichonse dera.
