Drift Velocity

Average and instantaneous current | Drift velocity | Mobility| Current density | Ohm's experimental law | Ohm's Law from drift velocity | Temperature dependence of resistivity for conductors | semi comductors and super conductors | Temperature dependence of resistance

A metal wire of length l is connected to an ideal battery of emf V and it is found that drift velocity acquired by the electrons is v_(d) . If the same wire is stretched to double its length then what will be the drift velocity of electrons?
