The problem: Apply Kirchhoff's loop rule for three loops and the junction rule for one junction for the circuit shown at the right. Do not solve for the electric currents.
Proposed solution:
+9V- (7 Ω)I- (6 Ω)I=0
+9V- (7 Ω)I- (3 Ω)I=0
- (6 Ω)I- (3 Ω)I=0
a. Identify any errors in the proposed solution.
b. Provide a corrected solution if there are errors.
