A gold wire has a 0.30 mm diameter cross section. Opposite ends of this wire are connected to the terminals of a 1.5 V battery. If the length of the wire is 5.5 cm, how much time, on average, is required for electrons leaving the negative terminal of the battery to reach the positive terminal? Assume the resistivity of gold is 2.44 10-8 Ω·m.
