Question

Find the current $i_b$ in given circuit below.

• A. 0.5 A
• B. 0.6 A
• C. 0.4 A
• D. 0.3 A

Hint:

In circuits with current sources, use nodal analysis or superposition to simplify.

Answer 1

The Correct Option is B

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
