The current carriers in a piece of semiconducting material have a charge of 1.6 x 10^-19C. Calculate the number of charge carriers entering the material per second when the current is 3 microamps so 3 x 10^-6 amps. ?

Please help and do it step by step all parts of questions and use:
T = time(s)
I=current (amps)
Q=net charge on object (Coulombs)
N=no electrons (and write if added or removed from object and how)
E=elementary charge

Same formula as on previous, this time, solve for N.
This has been going on for days. The current is the charge on a carrier times the number flowing by per second. Please "cylinder" post your attempts to solve these problems with your question. Your questions are all really the same.
