Kodi mosavuta recalculate milliamps kuti mikuza mawu, ndi mosemphanitsa

Nthawi zambiri, mu kuchita, pali kufunika recalculate milliamps kuti mikuza mawu. Tinathandiza zamagetsi ndi vutoli Kodi osadzuka. Koma akatswiri novice zoterozo mbiri mwina yomweyo kuyankha. Monga mbali ya m'nkhaniyi pofotokoza njira yosavuta angakwanitse kuchita opaleshoni.

kuchuluka thupi

Amperes - unit kuti quantifies mphamvu panopa. Mtengo wake zingadziŵike mwa muyeso mwachindunji ndi multimeter, Tester kapena ammeter (njira mwachindunji). The mwamphamvu panopa chimaonekera yekha ndi kugwirizana mndandanda mu dera magetsi a chingwe chida. Ngati chachiwiri, phindu lake angapezeke ndi kuwerengetsera kuchita (mozungulira njira). Ngati inu mukudziwa voteji ntchito kwa gawo la unyolo, komanso kukana ake, ndi okwanira kugawanitsa oyamba wachiwiri - ndipo timalandira ubwino ankafuna. Zochita si kawirikawiri ntchito mikuza mawu - ichi ndi wamtengo wapatali. Choncho ndikofunikira ntchito mayunitsi angapo - yaying'ono (10 ^-6) ndi milli (10 ^-3). Koma kuwerengetsera electrotechnical ayenera kumasulira iwo mu unit waukulu. (Mwachitsanzo milliamps kuti mikuza mawu). Taganizirani chitsanzo chotsatirachi. The voteji pa dera U = 6 V, ndi kukana R = 100 ohms. Kudziwa mphamvu ya I panopa pa izo ndi lamulo Ohm akuti:

Ine = U / R (1)

kumene:

• U - ndi voteji pa dera gawo V;
• R - kukana wa ohms gawo;
• Ine - mphamvu A. DC pa izo

Chifukwa cha anapezazo ife pezani = U / R = 6/100 = 0,06 A. Osati yabwino kwa chiwerengero cha maganizo. Choncho, n'kukhala mayunitsi angapo. Pankhaniyi yabwino kukhazikitsa phindu izi milliamperes. Chifukwa chaichi, phindu kupeza kuchulukitsa ndi 0,06 A 1000 ndi kupeza 60 MA. Mukhoza kuchita kutembenuka n'zosiyana - milliamps kuti mikuza mawu. Kuti tichite zimenezi, gawani 60 MA chikukwanira 1000, ndi onse a yemweyo 0,06 A. kutembenuka Ichi chikuoneka ngati milli ampere - 1000. Choncho, ife kugawanitsa kapena kuchulukitsa izo mwa nambala iyi. Ngati mukufuna kugwiritsa ntchito "yaying'ono" manambala oyambirira, muli kupita ku wagawo wina ndi mzake ayenera kuchulukitsa kapena akufufuta miliyoni.

ndondomeko kayesedwe

Monga tanena kale, chifukwa kuyeza amperage ntchito ammeters, multimeters ndi testers. Wamkulukulu molondola muyeso operekedwa ndi oyamba. Iwo kuyeza mtengo umodzi wokha ndipo lonse chimodzi chokha. Ndipo si yabwino kwambiri. Nayenso multimeters ndi testers imakuthandizani kuyeza pafupifupi onse mfundo magetsi, osati osiyanasiyana okha limodzi. Komanso, mu zipangizozi ndi luso kusinthana mayunitsi. Mwachitsanzo, chida limasonyeza kuti uthunthu ndi kuposa. Pankhaniyi, inu ndi kusinthana milliamps kuti mikuza mawu chotero kudziwa kufunika. The drawback waukulu testers ndi multimeters kuti mosiyana ammeters, cholakwa ali zambiri. Komabe, mu kuchita, amachita ntchito, monga izo zimapangitsa izo zovuta kupeza vuto ndi vutolo. chinthu chimodzi makamaka kugwirizana ndi zipangizo izi: kale kukhala wotsimikiza kuswa unyolo, anaonekera testers ndi multimeters, amene kuyeza mphamvu ya panopa m'njira contactless, mwachitsanzo popanda kulumikiza. Chotero njira ochuluka ntchito mu ntchito.

chidule

Kumasulira milliamps kuti mikuza mawu Pali njira ziwiri. Woyamba imakhala pochita kuwerengetsera masamu ntchito yapadera "1000" koyefishienti (nambala ya milli ampere). Yachiwiri njira zachokera ntchito zipangizo zapadera chingwe - Tester ndi multimeter. Ali masiwichi wapadera kuti amakulolani kutembenuza milliamps kuti mikuza mawu wopanda mavuto ndi mosemphanitsa. Kodi njira yabwino kwambiri ndi ntchito kuchita. Ngati pali mwayi wophunzira kuika mtengo ndi kuwerengetsa, ndiye ntchito chimodzimodzi njira imeneyi. Apo ayi, mayeso imagwiridwa, zotsatira zomwe, ndi kudziwa kuchuluka osadziwika.
