A battery has an internal resistance of 1.20 O and its open-circuit terminal voltage is 1.50 V. When a cylindrical wire 2.10 mm in diameter and 245 m long is connected across the terminals of this battery, the current in the circuit is 0.472 A. What is the resistivity of the material from which the wire is made?
