Почему тут после i1=i4 идет сумма i2+i3?И почему они равны???
i1=i4-это,т.к последовательное соединение,но почему оно равно параллельному суммированию i2+i3?
Объясните очень объемно и ясно,пожалуйста.

Объяснение: это невозможно объяснить объёмно, так как следует напрямую из первого закона Кирхгофа:

Сумма всех токов, втекающих в узел, равна сумме всех токов, вытекающих из узла.

Из этого следует, что i1 = i2+i3
