Question

Assume that the initial energy stored in the inductors of both figures is zero. Suppose that L1 = 15 mH and L2 = 17 ?H .

A) Find the equivalent inductance of (Figure 1) with respect to the terminals a, b.

Answer 1

The equivalent inductance calculation depends on whether the inductors are in series or parallel, but without a figure or additional information on their arrangement, a specific answer can't be provided.

Step-by-step explanation:

The student is asking about the equivalent inductance of a circuit given that two inductors, L1 and L2, are mentioned. Without a figure to reference, we cannot determine whether the inductors are in series or parallel, which is crucial to solving for equivalent inductance. However, given that the student assumes that the initial energy stored in the inductors is zero, this allows us to concentrate on finding the equivalent inductance without considering initial conditions. If L1 (15 mH) and L2 (17 µH) are in series, their inductances would simply add. If they are in parallel, the equivalent inductance (Leq) can be found using the formula 1/Leq = 1/L1 + 1/L2.
