Answer Posted / sunil yadav
the speed of current is the rate of flow of electrons in a
conductor.. n that is the DRIFT VELOCITY... the speed of
current being equal to the speed of light is a pure
misconception...
drift velocity=(mu)*E
mu= electron mobility; it's value depends on the type of
material..
