C: Analyzing Multi-Source Circuits
Solve the following problems. Answers are given at the end of this section.

1. Determine the magnitude and direction of the current flowing through R1 and R2 in the circuit shown above.

1. Determine the magnitude and direction of the current flowing through R1, R2, and R3 in the circuit shown above.

1. Determine the currents I1, I2, and I3 is the diagram above. Assume the internal resistance of each battery is r =1Ω. What is the terminal voltage of the 6 V battery?

1. I1 = 0.682 A

I2 = 0.4 A /

1. I1 = 0.055 A

I2 = 0.273 A
I3 = 0.218 A

1. I1 = 0.995 A

I2 = 0.276 A
I3 = 0.718 A
Vterm = 5.28 V
