Answer:
Choice a. Approximately on average.
Explanation:
The electric current through a wire is the rate at which electric charge flows through a cross-section of this wire.
Assume that electric charge of size flowed through a wire cross-section over a period of time
. The average current in that wire would be:
.
For this question:
, whereas
.
Therefore, the average current in this circuit would be:
.
However, the units in the choices are all in (for Amperes.) One Ampere is equal to one
. It will take some unit conversations to change the unit of
(coulombs-per-minute) to coulombs-per-second.
.
Hence, the most accurate choice here would be choice a.
