Bridge circuit network of five identical resistors connected between terminals X and Y.
Bridge circuit network of five identical resistors connected between terminals X and Y.
Five identical resistors, each of resistance \(R\), are arranged in a bridge network between terminals \(X\) and \(Y\), as shown in the diagram. Four resistors form two parallel branches with intermediate nodes, and a fifth resistor \(R_5\) connects these two intermediate nodes. Which option correctly identifies the equivalent resistance \(R_{eq}\) between terminals \(X\) and \(Y\) and justifies why no current flows through resistor \(R_5\)?
