XULOSA
Men xulosa qilib shuni ayta olamanki - ushbu labaratoriya ishidan o`zimga kerakli bilim va ko`niklamarni oldim.. NI Multisim dasturiy muhiti yordamida yordamida kuchlanish va tok manbasining tashqi tavsifini o’rganish tatbiq etdim. Labaratoriya ishi bajarish davomida kuchlanish va tok manbasining tatbiq etish uchun sxema va formulalardan foydalandim. Jadvalni kelib chiqqan natijalar bilan to’ldirdim.Va chiqan natijalar orqali Excel orqali grafiklar chizdim..Ushbu laboratoriyani bajarish davomida real mustaqil kuchlanish va uning ishlash prinsiplari to’g’risida to’liqroq ma’lumotlarga ega bo’ldim. Shuningdek, foydali ish koeffitsienti yuqori bo’lishi uchun manbaning ichki qarshiligi kichikroq bo’lishi kerak. Ichki qarshilik 0 bo’lganda biz uni ideal kuchlanish manbasi deya olamiz. Amalda esa buni iloji yo’q. Multisim dasturi orqali kerakli ishlar bajarilib jadvalga yozildi. Quvvat, tok kuchi va F.I.K ni o’rgandik. Ryuk ning ma’lum qiymatida Pyuk maksimal qiymatga erishadi. Fizika kursidan ma’lumki, Rich = R bo’lganda quvvat maksimumga erishadi. Grafik orqali buni ko’rishimiz mumkin. Men bu labaratoryani bajarganimdan juda mamnunman.

Xurmat bilan.
