In DAB circuit, the net emf and resistance becomes respectively as: 1 V and 3 ohms. with the battery sign equivalent to 2 V.
In DCB ckt., the net emf and resistance becomes, 2 V and 4 ohms respectively with the battery sign 3V.
 
Now assuming 0 volt emf in BD series we will apply emf formukla for parallel combination,
Emf => (-1/3 + 0/2 + 1/2)/(1/3 + ½ + 1/4)
           => 2/13 volts
 
Resistance equivalent => (1/3 + ½ + 1/4) => 2/13 ohms
 
Net current flowing in the circuit would be => I = V/R =  1 A.
