Let `/_\Q` be the net charge flowing across a cross-section of a conductor during the time interval `/_\t` [i,e. between times t and `(t+/_\t)`]. Then, the current at time t across the cross-section of the conductor is defined as

A

`l(t)=underset(/_\t tot)lim(/_\Q)/(/_\t)`

B

`l(t)=underset(/_\t too)lim(2/_\Q)/(/_\t)`

C

`l(t)=underset(/_\t tot)lim(/_\Q)/(2/_\t)`

D

`l(t)=underset(/_\t too)lim(/_\Q)/(/_\t)`
