A 1,200 mm long copper wire has a cross-sectional radius of 0.5 cm. (a) What is the resistance of the wire? (resistivity = 1.868 x 10* -8 at 30-degree Celsius, alpha = 0.0086). (b) What is the resistance at 60-degree Celsius? (C) If 350 mA of current flow through the wire, what does the voltage drop of the wire at 30-degree Celsius? And (d) What is the voltage drop per meter at 30-degree Celsius?
