Menene dokar kiyayewa wutar lantarki

Kamar yadda muka sani, daga makaranta kimiyyar lissafi Hakika, dokar kiyayewa wutar lantarki a cikin wutar lantarki na jikinsu. A duban farko shi iya ze cewa sanin wannan al'amari ne ma m magance su a cikin rayuwar yau da kullum. Bari yanzu mu magana game da abin da shi ne a zahiri da kuma inda yana yiwuwa su hadu da dokar kiyayewa wutar lantarki.

A halin yanzu ka'idar tsarin da takaice gardamar cewa cajin yan dako - electrons, shi ne daya daga cikin barga barbashi. Energy ba zai iya bace: a cikin sararin samaniya kawai da canji yakan faru. Saboda haka, dokar da kiyayewa da wutar lantarki. Yi tsammani cewa wani electron karkashin wani yanayi iya raba sauran gyara na barbashi (msl, photon da elusive neutrino) tare da an dace net cajin. Duk da haka, har yanzu da na aikin kimiyya ya musanta irin wannan yiwuwar, tun m kwarewa (da suka za'ayi da akai-akai) kasa. Ba abin mamaki sai su ce: cewa electron ne basa, shi ne inexhaustible ... The msar tambayar lokacin da wanzuwar barbashi ne a kalla 10 zuwa 22 digiri.

Ba asiri cewa jimlar lura da zarra ne sifili. Wannan shi ne saboda mummunan m dukan electrons da aka cika da kyau cajin na protons a tsakiya. Aikin juna neutralization, duk da haka zarra a matsayin dukan ne electrically tsaka tsaki. Hakika, idan ta samar da ƙarin makamashi (msl, zafi da kaya zuwa high yanayin zafi ko don shafa da alternating Magnetic filin), electrons a kan m falakinsu (valency) zai iya barin ta "istinbadi wuri". A wannan yanayin, wani abu ion da free electron. Amma yawanci, da samar da makamashi da an samu daga cikin barbashi an radiated a cikin nau'i na photons da kwayoyin halitta murmurewa barga tsari. A musamman harka - hada da abubuwa, inda wasu barbashi an raba ta biyu (ko fiye) atoms. A kiyayewa dokar da aka ma da za'ayi to cikakkiyar.

Amma baya ga takaice daga cikin yankin da mafi m rayuwa. A dokar da kiyayewa da wutar lantarki da aka yi amfani da ko'ina a cikin wutar lantarki injiniya lissafin. Alal misali, shi ne isa ya tuna da farko mulki Kirchhoff. A gaskiya, shi yana tabbatar da dokar kiyayewa wutar lantarki. Alal misali, a AC haihuwarka na uku-lokaci yanzu akai-akai amfani da hanyar na shugaba haɗi a wani star. A wannan lokaci uku conductors an haɗa ka da kumburi. Zai ze, babu makawa short-circuited tare da ci gaban da na yanzu da kuma hurawa na wani conductive abu. A gaskiya, wadannan na faruwa: a kowane irin kumburi Naira Miliyan Xari da igiyoyin ne ya daidaita da sifili. A lissafin (al'ada) inflowing igiyoyin suna dauke tabbatacce kuma mai fita - korau. A wasu kalmomi: I1 + I2 + I3 = 0, da kuma cewa shi ne ma gaskiya, I2 = I1-I3, da sauransu. A sauki sharuddan, da mai shigowa cajin iya ba ƙetare adadin fita daga kumburi. Idan karkashin irin wannan conductors haɗa da dokar kiyayewa zargin bai yi aiki ba, zai yi rubuce jari na cajin barbashi a shafin, da kuma shi ba ya faru.

Lantarki da kwayoyin halitta - wannan ba kawai yankin inda dokar kiyayewa cajin. Biology da kuma o ma ba a manta. Lokacin shahara photosynthesis (halittar kwayoyin halitta a chlorophyll hatsi a karkashin mataki na hasken rana) a lokacin da sha na haske jimla na masana'anta tsarin barin guda electron. Duk da haka, tun da chlorophyll kwayoyin haka yakan mallaki wani m cajin, "wõfintattu sarari" nan da nan cika da daya daga cikin free barbashi. A gaskiya, godiya ga dokar kiyayewa cajin iya zama a cikin nau'i na sararin duniya, to wanda muke duk saba.
