2.2 Reaktiv elementdagi io’tish toki va kuchlanishini operator usulda shisoblang.
2.3 O'tish toki va kuchlanishining hisoblab topilgan ifodasini 1-topshiriqdagi
1)1-
topshirikqdan sxema va uning parametrlari qiymatlarini olamiz.
2.1-rasm. Tekshirilayotgan zanjir.
2)reaktiv elementdagi o'tish toki va kuchlanishni operator usulda
hisoblaymiz. Hisobni quyidagi tartibda olib boramiz:
2.1) ta'sir funktsiyasining tasvirini aniqlash;
2.2) tok va kuchlanish shaqiqiy qiymat (original) laridan ularning Laplas
bo'yicha tasvirlariga o'tish va ekvivalent operator sxema tuzish;
2.3) tok va kuchlanishlarning tasvirlarini hisoblash;
2.4) aniklangan tasvirlardan haqiqiy qiymat (original) larga qayta o'tish;
3.1) ta'sirning (berilgan tokning) tasvirini aniqlaymiz.

3.2) Ekvivalent operator sxemani tuzamiz (2.2-rasmga qarang)
1-topshiriqqa asosan (kommutatsiyagacha bo'lgan rejimni hisoblash)
Uc(0)= 20 V
3.3) Kondansatorli tarmoqdagi tok va undagi kuchlanishning tasvirlarini
hisoblaymiz.
Hisob uchun kontur toklar usulini tanlaymiz.
2.2- rasm. Tekshirilayotgan zanjirning ekvivalent operator
sxemasi.
