3 – NAZORAT ISHI
Nazorat ishi mavzusi: Elektr toki. Elektr zanjiri
Nazorat shakli: Yozma ish
1. Uzunligi 10 m, ko’ndalang kesim yuzi 2 mm2 bo’lgan temir simning elektr qarshiligini hisoblang. Agar shu simni kuchlanishi 3 V bo’lgan manbaga ulansa, unday qanday tok kuchi hosil bo’ladi ? Temir uchun solishtirma qarshilik 0,1∙10-6 Ω∙m ga teng.
2. Elektr lampochkasi spiralidan o’tuvchi tok kuchi 0,5 A bo’lib, 6 V kuchlanishli manbaga ulangan. Lampochkaning elektr qarshiligini hisoblang.
3. Tok kuchi 32 μA bo’lganda 1 s vaqt ichida o’tkazgichdan nechta elektron o’tadi ? Elektron zaryadi 1,6∙10-19 C ga teng.
4. Elektr qarshiligi 20 Ω va 30 Ω bo'lgan o'tkazgichlar avval ketma-ket, keyin parallel ulandi. Ketma-ket va parallel ulashdagi umumiy elektr qarshilikni hisoblang.
