Question 15

A portable sensor in a simple circuit registers a total charge transfer of 84 μC84\text{ }\mu\text{C}84 μC passing a point over a time interval of 12 ms.

What is the average current in the circuit, expressed in milliamperes (mA\text{mA}mA)?

A

7×10−6 mA7 \times 10^{-6}\text{ mA}7×10−6 mA

B

7×10−3 mA7 \times 10^{-3}\text{ mA}7×10−3 mA

C

7 mA7\text{ mA}7 mA

D

7×103 mA7 \times 10^3\text{ mA}7×103 mA
