Explanation / Answer

Req = R1R2R3/R1R2+R2R3+R3R1 = 7.14. So, Current flowing out of the battery = I = 18 / 7.14 = 2.52 A

By current division rule, Curent through R2 = I2= I * (R1R3/R1+R3) / R2+(R1R3/R1+R3) = 0.9A

Similarly, I3 = I * (R1R2/R1+R2) / R3+(R1R2/R1+R2) = 0.9A

I1 = I- I2- I3 = 0.72A

voltage across R3 = 20*0.9 = 18V
