Elektronikadan Mustaqil ishi.
Murakkab doimiy tok zanjirlarini hisoblash

Savollar:
Sxemalari 3.1-3.50 - rasmlarda ko'rsatilgan elektr zanjirlarini 3.1-jadvalda ko'rsatilgan EYuK va qarshiliklari qiymatlari uchun quyidagi usullar bilan hisoblang:

- Kirxgofning birinchi va ikkinchi qonunlarga muvofiq toklarning qiymatlarini;
- kontur toklari usuli bo'yicha toklarning qiymatlarini;
- superpozitsiya usuli yordamida toklarni;
- R₄ , R₅ , R₆ qarshilik uchburchak sxemani yulduzchaga almashtirish orqali sxemani soddalashtiring va toklarni tugun potentsiallari usulida aniqlang;
- ekvivalent generator (Тевенин теоремаси) usuli bilan R₆ rezistoridagi tokni aniqlang.
