An ideal battery with potential difference \(\Delta V = 12\text{ V}\) is connected to a circuit consisting of five resistors, as shown in the diagram. Resistors \(R_1 = 2.0\text{ }\Omega\) and \(R_2 = 4.0\text{ }\Omega\) form the left branch, while resistors \(R_3 = 4.0\text{ }\Omega\) and \(R_4 = 2.0\text{ }\Omega\) form the right branch. A bridge resistor \(R_5 = 4.0\text{ }\Omega\) connects node \(\text{A}\) (between \(R_1\) and \(R_2\)) to node \(\text{B}\) (between \(R_3\) and \(R_4\)). What is the magnitude of the potential difference across resistor \(R_5\)?
