Current...please help!!! 1. The problem statement, all variables and given/known data In an ionic solution, 3.93×10^15 positive ions with charge +2e pass to the right each second while 9.01×101^5 negative ions with charge -e pass to the left. What is the magnitude of current in the solution? 2. Relevant equations I = Ch in Q / Ch in T 3. The attempt at a solution So I did... R = 1.6x10^-19 * 3.93x10^15 / 1 R = -1.6x10^-19 * 9.01x10^15 / 1 and then I added them...what am I doing wrong???
