Multiple choice question for engineering Set 1 1. Find the value of I1, I2 and I3. a) -0.188A, 1.5A, -1.19A b) -1.5A, -0.188A, 1.19A c) 1.5A, -0.188A, -1.19A d) 1.19A, 0.188A, 1.5A AnswerAnswer: c [Reason:] Using the matrix method: Matrix(3,-2,0) (I1)=(5) (-2,9,-4) (I2)=(0) (0,-4,9) (I3)=(-10) Solving this matrix equation, we get I1=1.5A, I2=-0.188A and I3=-1.19A….
