A 1,200 mm long copper wire has a cross-sectional radius of 0.5 cm. (a) What is the resistance of thewire? (resistivity = 1.868 x 10^ -8 at 30-degree Celsius, alpha = 0.0086). (b) What is the resistance at60-degree Celsius? (c) If 350 mA of current flow through the wire, what does the voltage drop of thewire at 30-degree Celsius? And (d) What is the voltage drop per meter at 30-degree Celsius?

Since we only answer up to 3 sub-parts, we’ll answer the first 3. Please resubmit the question and…
