Find current and tell me short trick in well mannered

Q. Find current 
                 

Dear Student, 
                         As in figure we can see  negative plate  of both  battery  connected 
                        so positive plates will have same potential ( As batteries are of same emf)
                        So net potential difference across resister will be zero
                     
                        $Current i=\frac{net potential difference }{equivalent resis\tan ce }=\frac{2-2}{2}=0$
