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.
