If two different wires having identical cross-sectional
Chapter 20, Problem 3(choose chapter or problem)
If two different wires having identical cross-sectional areas carry the same current, will the drift velocity be higher or lower in the better conductor? Explain in terms of the equation \(v_{d}=\frac{I}{n q A}\), by considering how the density of charge carriers \(n\) relates to whether or not a material is a good conductor.
