3. (25 points) If we apply a potential difference of 4.50 V between the ends of a wire that is 2.50 m in length and 0.654 mm in radius, the resulting current through the wire is 17.6 A. What is the resistivity of the wire material?

Step 1
Step 1: Recall the formula for resistivity, which is given by Ļ = V * A / (I * L), where Ļ is resistivity, V is potential difference, A is cross-sectional area, I is current, and L is length. Show moreā¦

You apply a potential difference of 4.50 $\mathrm{V}$ between the ends of a wire that is 2.50 $\mathrm{m}$ in length and 0.654 $\mathrm{mm}$ in radius. The resulting current through the wire is 17.6 $\mathrm{A}$ . What is the resistivity of the wire?

There's a $2.5-\mathrm{V}$ potential difference between opposite ends of a 6.0 -m-long iron wire $1.0 \mathrm{mm}$ in diameter. Assuming a uniform electric field in the wire, find (a) the current density and (b) the total current.
