Базовые элементы электрических цепей

It should also take into account the fact that two loop currents flow in adjacent branches belonging to two circuits. The voltage drop across consumers in such branches must be taken from each current separately, taking into account their direction.

4. We solve the obtained system of equations for the loop currents by any method and determine them.

5. We arbitrarily set the direction of the real currents of all branches and designate them. Real currents should be marked in such a way as not to be confused with contour currents. Single Arabic numerals (I1, I2, I3, etc.) can be used to number the real currents.
