A potential difference V is applied to a conductor of length l and diameter D.How are the electric field intensity E ,drift velocity Vd and the resistance R affected when (i)V is doubled (ii)I is doubled and (iii)D is doubled? Share with your friends Share 5 Govind answered this Electric field E is given byE=VlDrift velocity vd is given byvd=eEτm=eVmlτResistance R is given byR=ρlA=4ρLπD21 when V is doubled , E becomes doubled, vd becomes double and R remains unchanged2 when L is doubled, E becomes half, vd becomes half and R becomes double3 when D is doubled, E remain unchanged, vd is also unchanged and R becomes one fourth 4 View Full Answer
