I

+ -VR


I

5 I + 10 I + 7.5 I – 45 = 0

22.5 I – 45 = 0

I = 2 mA

• Which branch has the bigger current?

• If the voltage across the 10 is 5V, what is the voltage across the 4?

• What is the total resistance?

The 4 branch

5 V

VTH and RTH

VTH = open circuit voltage at the output terminal RTH = equivalent resistance when the

voltage/current source is turned offVTH = voltage across 4 k = 12 V

RTH = 12 k in parallel with 4 k = 3 k

12 V

3 k
