Answer 1
2.5 A


This answer is incorrect because the two numbers were multiplied together when they were supposed to be divided. Current is the time rate of flow of charge. Try using return to top























Answer 2
5.0 A

Incorrect

This answer is incorrect because the amount of charge is not equal to the current . These two measurments are not the same.
Current is the time rate of flow of charge. Try using return to top



























Answer 3
7.0 A

Incorrect

Current is the time rate of flow of charge. Try using return to top


























Answer 4
10. A

Correct


This answer is correct because the amount of the charge is divided by the time. So if you divide 5.0 coulombs by 0.50 seconds, you will end up with an answer of 10. A. You used  correctly. return to top


























What's this question really asking?

This question is really asking if you know how to use the definition of current. return to top
