                       To find ∆:


                        (1  +  j2)   (j2)
                       [                   ]
                          (j2)      (4 –  j)

                       ∆ = (1 + j2) (4 – j) – (j2) (j2) = 10 + j7







                       To find ∆ i1:

                        (10 < 45°)     (j2)
                       [                    ]
                             0        (4 –  j)

                       ∆ i1 = (10 <45°) (4 – j) – (j2) (0)    = 35.355 + j21.213




                          ∆ i1   (    .       +       .      )
                       i1 =     =                   =   3.369 – j0.237 A
                           ∆          (     +     )






                       To find ∆ i2:


                        (1  +  j2)   (10 < 45°)
                       [                        ]
                          (j2)            0


                       ∆ i2 = (1 + j2) (0) – (10 <45°) (j2)   = 14.142 – j14.142




                          ∆ i2   (    .       –       .      )
                       i2 =     =                  = (0.285 – j1.614) A
                           ∆         (     +     )
