                       Step 3:

                       Solve the equation in each mesh to obtain the values of i1 and i2.


                              5i1 + 1i2 = 12       --------------------------------- (1)

                              1i1 + 3i2 = 10       --------------------------------- (2)




                       Converting mesh equations into matrix form;

                       5i1 + 1i2 = 12       --------------------------------- (1)

                       1i1 + 3i2 = 10       --------------------------------- (2)












                       From the matrix we can find the value of ∆, ∆i1, ∆i2, i1 and i2.


                       To find ∆:

                        5 1
                       (     )
                        1 3

                       ∆ = (5 x 3) – (1 x 1) = 14




                       To find ∆i1:














                       ∆i1 = (12 x 3) – (1 x 10) =   26


                                26
                       i1 =  ∆ i1  =   = 1.857A
                            ∆   14
