Find the time of relaxation between collsion and free path of electrons in copper at room temperature. Given resistivity of copper=1.7xx10^(-8) Omegam, number density of electrons in copper =8.5xx10^(28) m^(-3), charge on electron=1.6xx10^(-19) C, mass of electron =9.1xx10^(-3) kg and drift velocity of free electrons=1.6xx10^(-4) ms^(-1) |
