Expert Solution

Voltage = 15 V

Equivalent Rsistance = 10 + 20 = 30 ohm = R

V = I*R

current through circuit I = V/R

I = 15/30 = 0.5 A

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
