Idan kana sha'awar a cikin tambaya na yadda da yawa watts da kW, amsar ba za ka samu, bayan karanta wannan labarin. Mene ne Watt? Wannan naúrar ikon ji soma da International ma'auni tsarin raka'a (SI). Yana samu da sunan da saboda da makaniki-kirkiro Scotch-Irish saukarsa James Watt, wanda Ya halitta a duniya tururi engine. Har 1882 a lokacin da mafi yawan ƙauyuka a horsepower aka yi amfani a matsayin babbar sashi ne na auna, da kuma kawai bayan da sabuwar dabara makanikai ko'ina (musamman a na'urar aikin injiniya) soma wani sabon naúrar na ikon - watts. A kimiyyar lissafi, ikon ne kuzarinsu na aiwatar da naúrar na lokaci, bi da bi, za su zama daidai wa daya Watt daya joule da biyu (W = J / s).

Yadda yawa watts a kilowatts

Mutane suna kullum fuskanci manufar da wutar lantarki a cikin gida. All kayan a cikin fasfo an saita zuwa da ikon amfani. Ko da a cikin na farko lagwanin, a gilashin flask rubuta .. 40 W, 60 W, 100 W, da dai sauransu, amma da obin na lantarki tanda ko da wani Injin, da darajar da aka dauke su yafi hakan: 500-1000 W kuma 2-2, 5 kW, bi da bi. Kamar yadda a wasu jiki da dabi'u, da prefix "kilo" na nufin dubu Musulunci. Wannan shi ne, na lamba darajar ikon auna a kilowatts, ninka ta 1000 ko matsar da gidan goma nufi ga dama alamar uku lambobi: don haka muna samun da wutar lantarki darajar a watts.

Saboda haka, tambaya na yadda da yawa watts kilowatts, mun samu wani unequivocal amsar: kW a daya dubu watts (1 kW = 1000 W). Bugu da ari misalai bincika lantarki rikodi iko. Ga 'yan misalai na yadda za a fassara nuna dabi'u:

• 2.5 kW = 2500 watts.
• 0.2 kW = 200 watts.
• 3.095 kW = 3095 watts.

Wani lokaci da ake bukata ikon naúrar, bayyana, a watts, tuba zuwa kilowatts. Mu tuna yadda da yawa watts da kilowatt haka aka sani da darajar raba da dubu. Ko dai wani waƙafi šaukuwa zuwa uku lambobi zuwa hagu.

• 2750 W = 2.7 kW.
• 70 W = 0,07 kW.
• 150 W = 0,15 kW.

Bari mu bincika irin wannan abu a matsayin "kilowatt-hour"

A kilowatt hours (ko Watt hours) da aka auna da wutar lantarki na amfani da naúrar hour. A matsayin misali, sama da na al'ada kwamfuta tare da wani ikon 0,65 kW. Bari mu ɗauka cewa ya yi aiki da sa'a daya. Ta yaya zan san yadda makamashi sosai ya kashe a wannan lokaci? Very sauki: 0,65 kW yawaita by 1 hour, 0,65 kWh. Saba stovattnaya kwan fitila, sa'a daya cinye 100 watts mulki, haka, kowace rana ta ci gaba da aiki da shi zai ciyar 2.4 kW. Yadda yawa watts kW, mun riga tattauna a sama.

Basic iyali lantarki masu amfani da

A halin yanzu, ko da m mutane suka fara tunani game da samar da makamashi tanadi - sun ki Lagwani kwararan fitila da kuma maye gurbin su da tattali haske kwararan fitila ko haske-emitting diode. Lokacin da ka zaɓi gida nema babban siga, wanda musamman nuna ayyukan yadda ya dace kayan. za ka iya samun irin wannan kayan aiki a kowane gidan ko Apartment, firiji, talabijin, kwamfuta, da baƙin ƙarfe, da wutar lantarki sintali. Ka yi la'akari da ikon amfani da aka ambata raka'a. Firiji yawanci aiki a kusa da nan kowane lokaci, ta kuzarinsu kudi jeri daga 0.7 zuwa 1.3 kW da rana - shi zai dogara ne a kan girman da na'urar da yanayi zazzabi. Kwamfuta, da sharadin cewa shi ba ya kashe a ranar iya ciyar har zuwa 13.5 kW. TV guda talakawan amfani da 2.5 kW for 24 hours. Duk da haka, babbar "spenders" ne dumama kayan: lantarki kafaffu, ruwa heaters, lantarki cookers da sauransu. Alal misali, wani lantarki sintali for 20-25 minti jan 1-1.2 kW, wanda za a iya kwatanta ta da ci gaba da aiki firiji. Kuma nawa makamashi ku ciyar?
