The resistance of gold wire used in circuits is usually negligible compared to the components in the circuit, and can be ignored. For long, thin wires, this is no longer true. Calculate the resistance, in ohms, of a length of gold wire, 46.6 cm long, with a cross sectional area of 2.5 mm2. The resistivity of gold is 2.35×10-8 Ω.m. Use 2 significant figures in your answer.
