As we know the relation , which tells us that current is equal to the flow of charge per unit time, that is in t seconds q amount of charge has flown or we can say that in 1 second amount of charge has flown.
We have studied the relation q = n× e
Where q is total amount of charge; n is the number of electrons; e is the amount of charge on 1 electron which has value 1.6 X 10-19 C.
And is always constant(n).
In this problem we have to find n that is number of electrons, so we have the value of current I = 1.6 A and time t = 1 sec , and time will be 1 sec if q = 1.6C , as ,
electrons will emerge out of the bulb in one second or per second.
