7- NAZORAT ISI
1- qator
1.Elektr zanjirdagi lampochkaga parallel ulangan voltmeter 6,5 voltni ko’rsatmoqda.lampochkadan 12 C zaryad o’tganda qancha ish bajaradi?
2.Zanjirdagi tok kuchi 0,5 A bo’lsa,9 minutda qancha zaryad oqib o’tadi?
3.10 s vaqt davomida o’tkazgichdan 24 C zaryad o’tdi.O’tkazgichdagi kuchlanish 12 V.O’tkazgich qarshiligini aniqlang.
2-qator
1.Elektr zanjiridagi lampochka spiralidan o’tayotgan tok kuchi 0,3 A ga teng.Lampochka spiralidan qancha vaqtda 360 c zaryad o’tadi?
2.Uzunligi 5 m,ko’ndalang kesimi 0,1mm bo’lgan alyuminiy simning uchlariga 2 V kuchlanish berildi.shu simdagi tok kuchini aniqlang.
3.zanjir berilgan qismining qarshiligi 24 Om va shu qismidagi kuchlanish 120 V bo’lsa,berilgan qismdan o’tayotgan tok kuchini toping.
