In a salt water solution a total positive charge of +20.0μC was observed to move past a point to the right in 4.0 seconds, and in the same time a total negative charge of -28μC was observed moving to the left.
(a) What was the rate and direction of negative charge flow?
(b) What was the rate and direction of positive charge flow?
(c) What is the conventional current? (value and direction)
