A 2.5 g wire has a density of 15.4 g/cm3 and a resistivity of 1.22 × 10−7 Ω · m . The wire has a resistance of 106 Ω . How long is the wire? Answer in units of m.
The wire is made up of atoms with molecular mass 22 g/mol. What is the drift speed of the electrons when there is a voltage drop of 201.4 V across the wire? Assume there is one conduction electron per atom. The fundamental charge is 1.602 × 10−19 C. Answer in units of m/s.
I correctly solved for the length (L=11.87m). Need help with finding drift speed.
