Closed circuit

In a closed circuit, there is a voltage source with U1 = 12 V and with an internal resistance R1 = 0.2 Ω. The external resistance is R2 = 19.8 Ω.
Determine the electric current and terminal voltage.

Correct answer:

I =  0.6 A
U2 =  11.88 V

Step-by-step explanation:

U1=12 V R1=0.2 Ω R2=19.8 Ω  I=U1R1+R2=120.2+19.8=35 A=0.6 A
U2=I R2=0.6 19.8=11.88 V
