Hints remaining: 2 Feedback: 0% deduction per feedback. 50% Part (b) If the current going through the center of the loop is 75 A, what is the current going through the top, in amps?Explanation / Answer
Apply KVL for upper loop
e1-(r1+R1 + R5)I1- ( r2+R2)(-I2)-e2= 0
24-(5+20+0.10) I1-(40+0.5)(-I2) -48 = 0 -------------------------( for a part)
(b)
put I2 = 75 A in the above equaiton and solve for I1
24-25.1 I1-40.5 (-75)-48 = 0
I1 = 120 A
