Ive tried two methods. The one in the textbook using I4=(R3/R3+R4)I2 and an online method from this video
. Ive followed both to a T and still it marks me wrong. Ive been working on this problem for nearly 2 hours now and cant get it. My initial answer was 0.53 using the method from the book and using the video I got 0.067. What am I doing wrong? Im losing my mind.
