If n, e, t and m denote the charge density, electronic charge, time of relaxation and mass of electron in a conductor, the resistivity is given by-

A

B

ne2τ m\frac { \mathrm { ne } ^ { 2 } \tau } { \mathrm {~m} }

C

neτm\frac { \mathrm { ne } \tau } { \mathrm { m } }

D

n2eτm\frac { \mathrm { n } ^ { 2 } \mathrm { e } \tau } { \mathrm { m } }

Answer

Explanation

Solution

10 parallel resistance each of value R/10

Ž Req = R/1010\frac { \mathrm { R } / 10 } { 10 } = 0.01 R
