We convert the current source into its equivalent voltage source of the
               network and redraw it as

               Remove the 6 Ω resistor across AB and determine V               OC ,

               We write,


                                   +20 V − 2I − 2I − 6I − 12 V = 0
                or,                     10 I = 8 V

                                             I = 0.8 A

                                   V OC  = +12 + 6 × 0.8 = 16.8 V
