Hi
The two circuit i am having trouble getting the correct answers and could someone see if my equations are correct.
Attachment: View attachment tutqns3.pdf
Question 1:
Mesh 1
24ix + 30(ix - i2) = 12
54ix - 30i2 = 12
Mesh 2
70i2 + 7ix + 30(i2 - ix) = 0
100i2 - 23ix = 0
Find ix by Mesh1 + Mesh 2 gives
ix = 225.95mA book's answer is 254.8mA
Question 2 equations
Short circuit with current sources
i1 = V1/10
i2 = (V1 - V2)/8
i3 = V2/5
Node V1)
4 + i2 = i3
Node V2)
2 = i1 + i2 + 4
Open circuit with voltage source
mesh:
8i1 + 12 + 5i1 + 10i1 = 0
P.S
