Since resistances are in series....equivalent rersistance = 20 +10 = 30 ohm =R current through circuit = V/R = 15/30 = 0.5 amp the potential difference across the 10ohm resistor in the figure = I *R(10) = 0.5 * 10 = 5 V the potential difference across the 20ohm resistor in the figure= I *R(20) = 0.5 * 20 = 10 V
