Explanation / Answer
a) suppose all currents are going to the right
top loop
9 - I1 23 + 65 I2 = 0
I1 = 9/23 + 65/23 I2
bottom loop
12 - I3 40 + 65 I2 = 0
I3 = 12/40 + 65/40 I2
so
9/23 + 65/23 I2 + I2 + 12/40 + 65/40 I2=0
I2= - 0.127 A
means I2 is going to the left
I1 = 9/23 + 65*-0.127/23= 0.0324
I3 = 12/40 + (65/40)*-0.127=0.0936 A
so answer is 0.127,0.0324, 0.0936
b)
so answer is I1 right, I2 left, I3 up
c)
now equations are
top loop
9 - I1 24 + 65 I2 = 0
12 - I3 41 + 65 I2 = 0
so we now get
9/24 + 65/24 I2 + I2 + 12/41 + 65/41 I2=0
I2 = -0.126 A
I1 = 9/24 + 65*-0.126/24=0.0338 A
I3 = 12/41 + (65/41)*-0.126 = 0.0929
so answer is 0.0338, 0.126, 0.0929
d) so answer is I1 right, I2 left, I3 up
