The potential difference across Vb - Va is 38 Volts

Considering the given circuit we have to apply Kirchoff's Voltage Law (KVL) in order to calculate potential difference across Va and Vb.

  Here it is given that current I = 1.5 A flows from point a to b. With reference to the direction of flow of current the 20V battery is considered of positive potential and the 12V battery is considered of negative potential.

Applying KVL :  Va - Vb = 20V + (1.5 × 20)V - 12V

                          Va - Vb = 38V
