Electric Current?

Electricity and Magnetism Level 2

If n 1 n_{1} electrons are moving from east to west per second, and n 2 n_{2} singly ionized helium atoms are moving from west to east per second with n 1 > n 2 , n_{1} > n_{2}, then find the conventional current (in ampere) and its direction.

Note : e e is the charge of an electron.

0 ( n 1 + n 2 ) e (n_{1}+n_{2})e from W → \rightarrow E ( n 1 − n 2 ) e (n_{1} -n_{2})e from E → \rightarrow W ( n 1 − n 2 ) e (n_{1}-n_{2})e from W → \rightarrow E ( n 1 + n 2 ) e (n_{1}+n_{2})e from E → \rightarrow W
