Question

Though the electron drift velocity is small and electron charge is very small, a conductor can carry an appreciably large current because (A) electron number density depends on temperature (B) electron number density is very large (C) relaxation time is small (D) drift velocity of electron is very large

Current I =ne AVd The large value of I is because of number density of free electrons in a conductor (n) which is of the order n = 1028 per m3

Q. Though the electron drift velocity is small and electron charge is very small, a conductor can carry an appreciably large current because

electron number density depends on temperature

electron number density is very large

relaxation time is small

drift velocity of electron is very large

Current I = $n e A V_{d}$
The large value of I is because of number density of free electrons in a conductor (n) which is of the order n = $1 0^{28} p er m^{3}$
