Ok, this was not a homework problem, but a question I had on a test for electrical engineering. The question was as follows;
"What is the inductor voltage at 9uSeconds."
Ok, the way I approached the problem, and was marked as being wrong. I said that I know the equation for an inductor is
V = L( delta current/delta time)
BUT, if you are only choosing the point 9uSeconds, which is ZERO amps on the chart, and not over a range, then the voltage must technically be zero also then...
I mean, if the question asked what is the voltage at 9uSeconds, as it passed through that point, then I would have answered differently.
Anyhow, I'm new to this whole thing, and I'm just trying to understand if I'm technically correct, or just way off... does an inductor STILL produce a voltage even if it has zero current?
Thanks for any response :)
