Final answer:
To solve this circuit problem, apply Kirchhoff's laws to find the values of I1, I2, and I3.
Step-by-step explanation:
To solve this circuit problem, we can apply Kirchhoff's laws. First, let's find the current flowing through each resistor. Applying Kirchhoff's junction rule at point A, we get the equation: I1 = I2 + I3. Next, let's apply Kirchhoff's loop rule in the upper and lower loops. In the upper loop, we have the equation: Vs - I1 * R1 - I2 * R2 = 0. In the lower loop, we have the equation: -I3 * R3 + I2 * R2 = 0. Now, substituting the given values and solving the equations will help us find the values of I1, I2, and I3.
