Answer #1

Going from B to A you...

drop potential across the first resistorof V = IR = 0.5 * 16 = 8volts

drop potential across the battery (go from + sideto - side) of 15 V

drop potential across second resistorof IR = 0.50 * 10 = 5volts

If you think of this like going downhill, you started atthe top at point B and went downhill

8 + 15 + 5 = 28 Volts

So B is higher than A by 28 volts and thedifference of VB - VA is + 28
