Hi,

This isn't so much of a home work problem just a request for clarification from those that are more intelligent than I. I actually just wrote the final for Basic Circuit Analysis and there was a question that left me totally stumped.

I've attached a VERY crude, much less complicated version of the question..er..in question.

We were given a network of inductors and asked to find the equivalent inductance between a particular set of terminals. Easy enough. We were then asked to find the energy stored in each individual inductor if a 2A current source is attached between the terminals.

My question then, is this (Have a look at the diagram): Since inductors act like short circuits in DC when at their steady state, can I (as I did in the exam) assume that the current from the source (I1) splits evenly through the two branches. So if I1 is 1A, then L3 sees .5 Amps and L1 and L2 both share .5A. Since they are in parallel they would both see .25 A.

And then w = (1/2)*L*i^2 for each of the L's with their respective i's.

Is that even close to correct? The question was a lot more complicated than the simple version that I showed you here, but it was worth like 5/100, so I can't see the solution being that tough.

Anyway, I would really appreciate even just a Yes or No answer to this.

Thanks Alot.
