igiciro cy'umuringa kuri calculatrice
Umuringa ni kimwe mu byuma bikoreshwa cyane mu nganda ku isi. Nibyingenzi mumashanyarazi, amashanyarazi, ibikoresho bya elegitoroniki, ubwubatsi, hamwe na sisitemu yingufu zishobora kubaho. Umuringa ukoreshwa kandi mu biceri, ibintu byo gushushanya, hamwe n'amavuta nk'umuringa n'umuringa.
Gusobanukirwa amanota y'umuringa
Umuringa ubuziranenge bupimwa nkijanisha. C11000 (99,99%) ni electrolytike ikomeye yumuringa, icyiciro gikunze gukoreshwa mumashanyarazi. OFE (Oxygene idafite Electronic, 99,99%) ikoreshwa muri elegitoroniki yo mu rwego rwo hejuru. Amanota yo hasi nka 99% na 90% akoreshwa mubikorwa bitandukanye byinganda.
Kubara Agaciro k'umuringa
Kugirango ubare agaciro k'umuringa, ugomba kumenya uburemere bwacyo. Umuringa usanzwe ugurwa kuri pound cyangwa kuri kilo muguhana ibicuruzwa.
Intambwe ya 1: Menya uburemere
Koresha igipimo nyacyo cyo gupima umuringa. Kubwinshi, umunzani winganda urasabwa.
Intambwe ya 2: Menya amanota
Menya urwego rwumuringa ukoresheje ibimenyetso, ibyemezo, cyangwa ibizamini. Ibyiciro bisanzwe birimo C11000, C10100 (OFE), hamwe nibisobanuro bitandukanye.
Intambwe ya 3: Kubara Agaciro
Agaciro = Uburemere x Icyiciro Cyiza x Igiciro Kuburemere
Ibiciro byumuringa mubisanzwe bivugwa kuri pound kumavunja ya COMEX cyangwa kuri toni metric kuri LME (London Metal Exchange).
Ibintu byo ku isoko
Ibiciro by'umuringa biterwa n’ibikenerwa n’inganda ku isi, ibikorwa by’ubwubatsi, amakuru y’inganda z’Abashinwa, itangwa n’abakora ibicuruzwa bikomeye nka Chili na Peru, hamwe n’ingufu z’ingufu zishobora kongera umuringa ukenera imirasire y’izuba, ibinyabiziga by’amashanyarazi, hamwe n’umuyaga w’umuyaga.
