4.
The equation for loop currents I1 and I2 are __________
Answer: Option
Explanation:
k = 0.8
∴ M = kL1L2 = 0.83 x 2 = 1.95 H
Apply KVL to loop 1
200∠0° = (j5 + 5 + j2 - j3)I1 + 1.95I2
∴ 200∠0° = (5 + j4)I1 + j1.95I2
Apply KVL to loop 2
0 = (5 + 3 + j3)I2 + j1.95I1
0 = (8 + j3)I2 + j1.95I1
0 = j1.95I1 + (8 + j3)I2
∴ The loop equations in matrix form are
