Me pēhea te ki te ngāwari tatau anō milliamps ki Amps, me hurihia

Tino maha, i roto i te mahi, i reira he he hiahia ki te tatau anō milliamps ki Amps. ite matou electricians ki tenei raruraru e kore e ara ake. Otira kia kore whakahoki tonu tohunga tauhou o te kōtaha taua. Hei wāhanga o tēnei tuhinga ka whakaahua i te ara māmā, me te utu ki te mahi i tenei mahi.

rahinga tinana

Amperes - he kōwae e quantifies te kaha o te nāianei. Ka taea te whakaritea tona uara i roto i ine tika ki te multimeter, hei whakamatau iahiko (tikanga tika) ranei. Ko te kaha o nāianei whanganga te anake e te hononga raupapa i roto i te ara iahiko hiko o te mea ruri. I roto i te take tuarua, ka taea te kitea tona uara i tātaitanga e mahi ana (tikanga autaki). Ki te matau koutou ki te ngaohiko tono ki te wahi o te mekameka, me te tona ātete, he rawaka ki wehe te tuatahi ki te tuarua reira - ka whiwhi tatou i te uara e hiahiatia ana. I roto i te mahi Amps kore pera maha whakamahia - he he uara nui tenei. Na reira ko te reira e tika ana ki te whakamahi i wae maha - moroiti (10 ^-6) me Milli (10 ^-3). Ko hoki tātaitanga Electrotechnical Me ki te iriti ratou ki te kōwae matua. (Milliamps tauira ki Amps). A feruri i te hi'oraa e whai ake nei. Ko te ngaohiko i runga i te ara iahiko U = 6 V, me te ātete R = 100 ohms. Te whakatau i te kaha o te ahau o nāianei i runga taua mea i te ture a Ohm:

Ahau = U / R, (1)

te wahi:

• U - te ngaohiko i te V ara iahiko wahi;
• R - ātete o te ohms wahi;
• Ahau - te mana A. DC i runga taua mea

Ka rite ki te hua, te tātai whiwhi tatou = U / R = 6/100 = 0,06 A. E kore rawa watea ahau mo te maha o perception. Na reira, kua tahuri te reira ki wae maha. I roto i tenei take ko reira watea ki te whakauru i tenei uara i roto i milliamperes. Hoki tenei whakaaro, whakanuia te uara whiwhi e 0,06 te 1000, me te whiwhi 60 mA. Ka taea e te mahi koe i te faafariuraa whakamuri - milliamps ki Amps. Hoki tenei wāhanga o 60 mA he ranea hoki 1000, ka whiwhi katoa o te taua 0,06 A. kitea tēnei faafariuraa te rite wae iahiko Milli - 1000. Na reira, wehe matou tini reira e tenei tau ranei. Ki te kei te whakamahi koe i te "moroiti" kuhimua, whai koe ki te haere atu i tetahi wae ki tetahi kia whakanuia me wehea e kotahi miriona ranei.

tukanga inenga

Mai tei tapaohia, mo ine i te amperage whakamahia iahiko, multimeters me testers. Rawa tika inenga whakaratohia e te tuatahi o ratou. whanganga ratou tetahi anake uara me kotahi anake tauine. A ehara i te mea tino watea. I roto i te tahuri, multimeters me testers taea koe ki te ine i tata katoa uara hiko, a kahore noa i roto i te kotahi ngā. Hoki, i roto i enei whakaaro i te kaha ki te whakawhiti wae. Hei tauira, tohu te mea e nui te awhe te. I roto i tenei take, whai koe ki te whakawhiti milliamps ki Amps me te kupu ako i te uara. Ko te drawback matua o testers me multimeters ko e rite ki iahiko, ratou te hapa nui atu e. Otiia tonu, i roto i te mahi, kei te maha whakamahia ratou, rite hanga reira reira ngāwari ki te kitea te raruraru, me te whakatika i te reira. Kotahi te mea nui ake e pā ana ki enei whakaaro: mua ki te ia kia tino u ki te wahi i te mekameka, testers puta nei me multimeters, e ine i te kaha o te nāianei i roto i te tikanga contactless, arā, kahore he hononga. Kei te whakamahia piki he otinga taua i roto i te mahi.

whakarāpopototanga

Whakamāoritia milliamps ki Amps E rua huarahi. Ko te tetahi tuatahi ngā i roto i te mau ana i roto i ngā tātai tauhanga te whakamahi i motuhake "1000" tau whakarea (maha o Milli wae iahiko). E hāngai ana te tikanga tuarua i runga i te whakamahi o ngā taputapu ruri motuhake - hei whakamatau me te multimeter. E ratou whakakā motuhake e tukua ki a koe tahuri milliamps ki Amps, kahore raruraru me te hurihia. Ko tēhea te ara, ko te atu watea, me te whakamahi i roto i te mahi. Ki te kahore he ha faingamālie ki te ako i te uara i whakaritea mā te tātai, ka whakamahi i rite tenei tikanga. Te kore, kua whakamana i te whakamātautau, te hua o nei, me te mohio ki te rahinga unknown.
