Current Electricity Problems - Numerical 04

What is the drift velocity of electrons in a copper conductor having a cross-sectional area of 5 x 10^-⁶ m² if the current is 10A? Assume that there are 8 x 10²⁸ electrons/m³A.

Suggested solution:

Suggested solution:

Drift velocity, V_d = ?

Cross-sectional area, A = 5 x 10^-⁶ m²

Current, I = 10 A

Number density of free electrons, n = 8 x 10²⁸ electrons/m³

We know that
