Exercise 10

Network with two sources

Theory used: Kirchhoff's laws Solving a multi-loop circuit

An ideal source with $E_{1} = 9.0 V$ in series with $R_{1} = 1.0 Ω$ and an ideal source with $E_{2} = 3.0 V$ in series with $R_{2} = 2.0 Ω$ are connected between the nodes $A$ and $B$ with the positive terminals toward $A$ ; $R_{3} = 4.0 Ω$ is connected between the same nodes. Compute the currents in the three branches, with their directions.
