Current begin mathsize 14px style I end style passing through loop that consists of 1 V cell and two 2Ω resistor is
 
begin mathsize 14px style I end style = 1 V / (2+2) Ω  = 0.25 A
 
Potential difference VCD across the points C and D is
 
VCD = - 2 × 0.25 = - 0.5 V
 
(Point D is at higher potential )
 
Potential difference across A and B is
 
VAB = ( 4 - 0.5 V + 2 ) V = 5.5 V.
