My question is: Those wires where there are no resistances, namely those two which are between resistances connected in parallel, cannot carry current, isn't it, or they would blow. Since their resistance is almost zero, the dissipated power would be [tex]\epsilon ^2/r=+\inf[/tex]. Am I right? Thanks in advance, pals.

Exactly backwards. They will carry all of the current between the two points and none will flow through the resistors. Since there can be no potential difference between the two points they connect. You can basically take out your eraser and remove resistances that connect two points joined by a conductor.
