You are constructing a circuit in your predecessor’s notes to try to verify some of their results. The circuit in their notes shows a copper wire with diameter of 0.5 mm, but you only have aluminum that you can draw to any diameter you need (see https://www.youtube.com/watch?v=Q2l6r6751IM). What diameter should you specify to production staff to get the resistance that you need over the same length in the circuit?
The resistivity of the copper wire is
And the resistivity of the aluminum wire is
The resistance of the copper wire is therefore
And the resistance of the aluminum wire with the same length but different cross-section is
Both the resistance are equal. i.e
Putting the values
So, the diameter of the aluminum wire must be 0.628 mm to get the desired results.

You have a lump of copper with a mass of 1.8 grams. Copper is ductile so you can draw it into a cylindrical wire. You draw it into a wire with length L and diameter D so that it has a resistance of 2Ω. What is the length of the wire in m and the diameter in mm? Hint: you may need to look up some properties of copper!
If all questions can be answered thank you! 5. [-/1.42 points] DETAILS MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Residential building codes typically require the use of 12-gauge copper wire (diameter 0.205 cm) for wiring receptacles. Such circuits carry currents as large as 20.0 A. If a wire of smaller diameter (with a higher gauge number) carried that much current, the wire could rise to a high temperature and cause a fire. (Table of resistivities) (a) Calculate the rate at...
You want to produce three 2.00-mm diameter cylindrical wires, each with a resistance of 4.00 Ω at room temperature. One wire is gold, one is copper, and one is aluminum. What will be the length of the gold wire? What will be the length of the copper wire? What will be the length of the aluminum wire? Gold has a density of 1.93 ×× 1044 kg/m3kg/m3. What will be the mass of the gold wire? If gold is currently worth...

Please write the python functions Problem: Electric wire (Figure is a cylindrical conductor covered by an insulating material. Figure 2 shows the structure ofa single conductor. The resistance of a piece ofwire is given by the formula: A d where ρ is the resistivity of the conductor, and I (in meter), A, and d (in meter) are the length, cross-sectional area, and diameter of the wire. The wire diameter, d, is commonly specified by the American Wire Gauge (AWG). Which...
How to do these two problems 3. -1 points OSColPhys2016 20.1.WA.008 My Notes Consider a copper wire with a diameter of 2.51 mm. (a) What is the drift speed of the electrons in the copper wire when a current of 11.0 A flows through it? Assume that each copper atom contributes one free electron to the metal. The density of copper is 8.92 g/cm3 m/s (b) How does this drift speed compare to the random rms speed of an electron...
The most common component of a circuit is a resistor. A resistor is a device which resists electrical flow in a circuit. If you think of water flowing, a water resistor is a waterwheel; it reduces the flow while getting something useful out of the flow. We’ll make a few predictions before we start. Answer these questions on your whiteboard. Imagine a resistor in a circuit with current flowing around the circuit. The resistor is simply a wire of a...
