Question:

In Figure P31.70, determine the magnitudes of the currents $I_{1}, I_{2}$, and $I_{3}$ and whether the direction shown for each current is correct or should be reversed. Assume that $R_{1}=8.0 \Omega, R_{2}=8.0 \Omega, \mathscr{E}_{1}=6.0 \mathrm{~V}, \mathscr{E}_{2}=6.0 \mathrm{~V}$, and $\mathscr{E}_{3}=9.0 \mathrm{~V}$.
