Задача 2
Расчет несложной цепи постоянного тока
Определить ток I3 через сопротивление R3 приведенной на рис. 2 схемы, используя методы:
1) эквивалентных преобразований;
2) эквивалентного генератора (активного двухполюсника);
3) узловых потенциалов;
4) суперпозиции (наложения).
Данные для расчета взять из таблицы 2.
