Yintoni ombane inyathelo?

Iipali iingcingo ezihamba imigca amandla zibe attribute exhaphake kakhulu kubume ihlabathi mihla abaninzi babo nje awuboni. Nangona indawo ephezulu izinikezeli ukuthintela ukuchukumisa ngengozi, ukuba, nangona kunjalo, igcwele ingozi enokwenzeka. Wonke ukhumbula imeko ukususela ebuntwaneni bakhe, xa abazali bakhe babona wire eyaphukileyo gangalala emhlabeni, uzama ukufumana le ndawo, "indlela yeshumi." Oku kuthintela ugesi, njengoko ombane linyathelo kuyancipha kunye umgama. Sonke siyazi ukuba akunakwenzeka ukuba aye ngcingo ezaphukileyo. Noko ke, loo ombane inyathelo eyaziwa kuphela kubantu ikharakhtha eyahlulayo. Eli nqaku liza kuzama ngakumbi ukuqonda lo mbuzo, ukucacisa, ngokoqobo, "kwi iminwe".

Ngoko inyathelo ombane - kukho umahluko enokubakho phakathi kwemilenze, okanye oko kuyinyaniso kananjalo ukuba, phakathi iingongoma ezimbini (okanye ngaphezulu) wesikolo bebekwe ngokwahlukeneyo omnye komnye mgama pitch. Xa ingcaciso iinkqubo ezininzi Electrical Engineering basoloko besebenzisa isifaniso amanzi. Eneneni, kwezinye iimeko, ukuthelekisa umbane kunye namanzi kwamkelekile kakhulu, njengoko lula ukuqonda iinkqubo. Siza kuqhubeka.

Khawube nomfanekiso-ngqondweni yenye yeentsika yaphuka umgca emntwaneni kwaye ekupheleni wire wawa ombane komhlaba. Ukuba ucingo - isigodlo, kwaye ngoku - amanzi, endaweni zoqhagamshelwano phantsi liya kuba kuqokobhe. ubukhulu yaso izowuni liqhele apho umntu ukuzinyela iinyawo. A chibi kuyilwa kuba amanzi akakwazi yonke nangoko bathele umhlaba. Ubungakanani wokusasaza izowuni ixhomekeke kubungakanani bamanzi agqitha kombhobho nganye kwexesha unit.

Ke kaloku, emva kagesi. ombane Umthombo yenza umahluko enokubakho phakathi amanqaku amabini umgca, kwaye, ukuba phezulu ombane kunye nexabiso langoku le yangoku, kokukhona ummandla ingozi ezi ngcingo uqhelile. Imbonakalo "izadunge" ngenxa ukuxhathisa eliphezulu ohmic umhlaba; ngoku loop komhlaba (ngokwe æ 4 Ohm) indawo wokusasaza kuba ncinci okanye engekho kwaukubakho.

Masithi ecaleni kwicingo eyaphukileyo uyindoda. Ngenxa yomgama phakathi kweenyawo, kukho ingozi umahluko. Kwaye ngenxa yenkcaso emzimbeni - kwaye umsinga wombane. Enyanisweni, oko kuthetha ukuba ukukhatywa ngumbane. Kwaye, ukuba emva ukhatywa ngumbane luwela umntu (ngokupheleleyo okanye esandleni), oko kuwuvule kuphela imeko kuba ukunyuka inyathelo ombane. Ukongeza, ukuba indawo nkqo umzimba, uhamba kunye aya "ngomlenze - ngonyawo," ukuba emva kokuwa amanye amatyathanga kwakheka, nto leyo uwele entliziyweni, sizenza kubomi benzeke. Kulula ukuqonda ukuba izilwanyana (iinkomo, amabhere, amahashe), ivaleleke kummandla ukusasazeka lwangoku, basengozini enkulu ngaphezu abantu, ngenxa yokuba umgama phakathi ngaphambili kunye nemazi yexhama imilenze ixesha elide, ngoko ke, le ombane inyathelo kuyingozi kakhulu ngakumbi.

Ukusuka yonke le sinokwenza izigqibo ezininzi:

• ukuba ungena indawo yangoku cula ucingo eyaphukileyo (okanye ukusilela) kuyo nayiphi na imeko akanako ukunikela kwi nokungoyiki abaleke. Xa ibaleka ematheni kumgama uba mkhulu kwinyathelo, ngokulandelelana, kuyanda umthamo. Ingakumbi, ekubeni umntu uzama ukuya kude kulo mthombo lwangoku, inyathelo ombane buthi bube nobungozi ngakumbi;
• ekubumbeni ukusasaza zone nga kwahluka uluhlu somahluko conductivity lomhlaba.

Ukushiya ngaphandle kwebanga le ombane inqwanqwa unokuba izinto non-conductive (umz, ikholoni ibhodi eyomileyo); tsiba ngonyawo olunye (kulo mzekelo, akukho mahluko okunokwenzeka); okanye chu uphume, isongiwe yodwa iinyawo kunye.
