Question

10^9 electrons pass through a conductor from poin A to B in one millisecond.find the value of current and its direction.

Answer 1

The units of current is Ampere are by definition

1 Ampere = 1 Coloumb / 1 second

So you need to convert the two quantities you have into Coloumb and seconds and calculate.

Hint: the charge on an electron is \( e=1.6 \times 10^{−19} \) Coloumb.
