Решение:
Для решения этой задачи, мы можем использовать закон Ома, который гласит, что сила тока (I) в цепи равна напряжению (U), деленному на сопротивление (R): I = U / R.
У нас есть следующая схема:

Мы знаем, что R1 = R2 = 20 Ом и R2 = R4 = 10 Ом, а также I = 1 А.
Мы можем рассчитать общее сопротивление цепи, заменив параллельные резисторы R1 и R2 на их эквивалентное сопротивление Rp:
1/Rp = 1/R1 + 1/R2 1/Rp = 1/20 + 1/20 1/Rp = 2/20 1/Rp = 1/10 Rp = 10 Ом
Теперь мы можем рассчитать общее сопротивление цепи, заменив параллельные резисторы R2 и R3 на их эквивалентное сопротивление Rpq:
1/Rpq = 1/R2 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R3 1/Rpq = 1/10 + 1/R
