Homework Statement


"Use the equation I=nAve to justify why charges travel faster in semiconductor than in metallic conductor. Assume that the dimensions and current are the same. "



Homework Equations


I=nAve
I know I = current, n = number density, A= cross sectional area v= drift velocity and e = charge of electrons


The Attempt at a Solution


Is metallic conductor denser than semiconductor, hence the drift velocity is lower? Thanks in advance.
