I read in some book that speed of electon in aconductor is about 1x10^-6ms^-1 can this speed be changed by changing the current if yes why ,,,,,,,,if no why

Dear aditya,

Electrons are the charge carriers in metals and they follow an erratic path, bouncing from atom to atom, but generally drifting in the opposite direction of the electric field. The speed at which they drift can be calculated from the equation:

where

I is the electric current

n is number of charged particles per unit volume (or charge carrier density)

A is the cross-sectional area of the conductor

v is the drift velocity, and

Q is the charge on each particle.
