Two resistors

Two resistors 20 Ω and 60 Ω are connected in series and an external voltage of 400 V is connected to them. What are the electrical voltages on the respective resistors? Please comment!

Correct answer:

U1 =  100 V
U2 =  300 V

Step-by-step explanation:

R1=20 Ω R2=60 Ω U=400 V  R=R1+R2=20+60=80 Ω  I=U/R=400/80=5 A  U1=I R1=5 20=100 V
U2=I R2=5 60=300=300 V   Verifying Solution:  R1:R2=U1:U2 r1=R1/R2=20/60=310.3333 r2=U1/U2=100/300=310.3333 U=U1+U2
