Question
In the circuit of of Figure P 18.22, the current $I_{1}$ is 3.0 $\mathrm{A}$ and the values of $\boldsymbol{E}$ and $R$ are unknown. What are the currents $I_{2}$ and $I_{3} ?$
Step 1
0 A. We apply Kirchhoff's voltage law (KVL) to the second loop. KVL states that the algebraic sum of voltages in a loop is equal to zero. We assign polarities to the components in the loop based on the direction of the current. Since $I_{2}$ is moving from A to B Show more…
