manishk,you would have asked this question in the reverse
order as why current direction is always denoted in the
direction opposite to the elctron flow..
Because current is a flow of electron (we all
know).electron is a cause & current is the effect .Whenever
voltage is applied across the conductor ,the free electros
starts to flow through it, depend on the polarity of the
applied voltage.But for our theoretical calculations ,we
consider the current in the opposite direction .
