Homework Statement



A 10-ohm resistor has a constant current. If 1200 C of charge flow through it in 4 minutes what is the value of the current?
A) 3.0 A
B) 5.0 A
C) 11 A
D) 15 A
E) 20 A


The Attempt at a Solution



I get B as an answer. I=(Q/t). I= 1200C/ (4 * 60) = 5.0 A
The book says the answer is D. I thought the problem provided to much information. Can someone explain how D might be an answer.

Your method and answer are correct; answer D is not. The value of the resistance is irrevelant to the question asked, but don't let that distract you. :wink:
