Calculating the Current Through a 10-ohm Resistor

    Current Resistor
Click For Summary
To calculate the current through a 10-ohm resistor with 1200 C of charge flowing in 4 minutes, the formula I = Q/t is applied. The calculation yields I = 1200 C / (4 * 60) = 5.0 A, which is option B. Despite the book stating the answer is D, the method used is correct, and the resistance value does not affect the current calculation in this context. The confusion arises from the book's incorrect answer rather than the calculation itself. The correct current through the resistor is indeed 5.0 A.

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:
