A schematic diagram of a DC circuit containing a 10 V battery and five resistors arranged in a bridge network. The battery is on the far left, oriented vertically with its positive terminal at the top labeled 10 V and negative terminal at the bottom connected to ground at 0 V. Wires extend from the battery to a diamond-shaped bridge. The top junction is labeled A, and the bottom junction is labeled B. Resistor R_1 (2.0 \Omega) is in the upper-left branch between node A and left node C; resistor R_2 (6.0 \Omega) is in the upper-right branch between node A and right node D; resistor R_3 (6.0 \Omega) is in the lower-left branch between node C and node B; resistor R_4 (2.0 \Omega) is in the lower-right branch between node D and node B. A horizontal central branch connects node C and node D, containing resistor R_5 (2.0 \Omega). No other labels, lines, text, or axes appear.
A bridge circuit connected to a DC voltage source.
An ideal \(10 \text{ V}\) battery is connected to a bridge network consisting of five resistors, as shown in the diagram. The resistor values are \(R_1 = 2.0 \text{ }\Omega\), \(R_2 = 6.0 \text{ }\Omega\), \(R_3 = 6.0 \text{ }\Omega\), \(R_4 = 2.0 \text{ }\Omega\), and \(R_5 = 2.0 \text{ }\Omega\). What is the magnitude of the electric current flowing through the central resistor \(R_5\)?
