The amount of charge transported by a current of 12 mA during a period of 3 s is:
A) 36 mC
B) 250 mC
C) 4 C
D) 36 C

Question

Quizplus · Accepted Answer

The amount of charge transported is given by the formula Q=I*t, where Q is the charge in Coulombs, I is the current in Amperes, and t is the time in seconds. 
Substituting I=12 mA=0.012 A and t=3 s, we get 
Q=0.012 A * 3 s = 0.036 C = 36 mC. 
Therefore, the correct choice is A.
