To determine the equivalent circuit (input) circuit resistance with respect to the power source terminals, current and voltage drop in all branches of the chain. Create balance of power.

E = 30 V, R0 = 0,2 ohms, R1 = 2 Ohms, R2 = 0 ohms, R3 = 3 ohms, R4 = 5 ohms, R5 = 2 ohms, R6 = 2 ohms, R7 = 4 ohms, R8 = 5 Ohm, R9 = 0 ohms, R10 = 6 ohms, R11 = 7 ohms, R12 = 5 ohms, R13 = infinity, R14 = 2 Ohm, R15 = 3 ohms, R16 = 4 Ohms, R17 = 5 ohms

Calculation of DC link by folding and equivalent transformations. The balance of power.
