1. The problem statement, all variables and given/known data "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. " 2. Relevant equations I=nAve I know I = current, n = number density, A= cross sectional area v= drift velocity and e = charge of electrons 3. The attempt at a solution Is metallic conductor denser than semiconductor, hence the drift velocity is lower? Thanks in advance.
