№3 Laboratoriya ishi
Reostat yordamida tok kuchin rostlash
Ishning maqsadi: Ampermetr va voltmetrdan foydalanib o`tkazgichning qarshiligini o`lchab o’rganish. O`tkazgichning qarshiligi undagi tok kuchini va uning uchlarindagi kuchlanishlariga bo ylanishli emas ekanligini tajriybada ko’ramiz.
Kerakli jihozlar: akkumulator, reostat, ampermetr, voltmetr, kalit va ulovchi
simlar.
