In a certain material there is a current of 16 A flowing through a surface to the left, and there is an equal amount of positive and negative charge passing through the surface producing the current. How much negative charge passes through the surface?
A) 16 C/s toward the left
B) 16 C/s toward the right
C) 8 C/s toward the right
D) 8 C/s toward the left
