Find the current $i_b$ in given circuit below.
Step 1: Apply KCL or mesh analysis.
Use loop current or nodal methods considering the controlled current source.
Step 2: Solve for $i_b$.
Proper analysis shows $i_b = 0.6$ A
Conclusion: $i_b = 0.6$ A




The supply voltage magnitude \( |V| \) of the circuit shown below is ____ .
A two-port network is defined by the relation
\(\text{I}_1 = 5V_1 + 3V_2 \)
\(\text{I}_2 = 2V_1 - 7V_2 \)
The value of \( Z_{12} \) is:
