The numerical problems in this post are based on the drift velocity of electrons and electric current. Electric Current is expressed as I = nAve ( see the derivation of electric current and drift velocity equation ) Numerical problems on Drift velocity of electrons and electric current 1 ] A copper wire has a cross […]

## How Small drift speed of electron causes high-speed electric current?

Most charge carriers, like electrons, move slowly. how the Small drift speed of electrons causes a high-speed electric current?

## How to Derive the relationship between Current and drift velocity

So this is the equation describing the relationship between current(I) and the drift velocity(v). Derivation of drift velocity equation
