[Drift velocity] Factors affecting velocity
1. Is the charge density (No. of charges/volume) constant for a specific material ? e.g. Copper has a constant charge density no matter how big it is ?
2. Why someone told me that increasing the cross-sectional area of a wire will not affect its drift velocity ? The resistance will be reduced and the electrons can move faster, isn't it ?
