But isnt v_{d} independant of L?
i mean v_{d} = 1 eE τ2 m. Right?
- Niraj kumar Jha By making length 2l. Resistance becomes twice hence current becomes half so drift vel. should be V/2Upvote·0· Reply ·2014-04-14 21:31:39
Case 1)L=12aT^{2}
and Vd=L/T
Case 2) 2L=12at^{2}
time for accn of e is diff in the 2 cases, so Vd will be affected
and using the formula i=neA(Vd) , where A is area and equating volume, new Vd can be obtained
