The equivalent inductance between A and B is equal to
Options
- A4 5 H
- B5 4 H
- C3 10 H
- D15 H
Correct answer
A. 4 5 H
Step-by-step solution
Equivalent inductance calculation between points A and B The circuit simplifies when recognizing that all four inductors connect between common nodes N (A and D) and M (C and B). This places the 2H, 3H, 4H, and 6H inductors in parallel. The equivalent inductance L_ eq for parallel inductors satisfies: 1 L_ eq = 1 2 + 1 3 + 1 4 + 1 6 Combining fractions with common denominator 12: 1 L_ eq = 6 + 4 + 3 + 2 12 = 15 12 = 5 4 Thus, L_ eq = 4 5 H, corresponding to option A.
