# Homework Help: Simple Electrical Trick Question Maybe?

1. The problem statement, all variables and given/known data

I had posted another thread a week ago where I was given a function q(t) that t was defined in millisecond, and I had to evaluate q(t) at 0 and infinity then I had to do the same thing when I found the current I(t) in Coulombs/ms, Now i have do the same further more by finding P(t)..power...and W(t) watt-second/energy used, I believe

3. The attempt at a solution

By simply converting my equation I(t) to seconds I was able to find the amount of amperes a second, however, to find power there seems to be a missing "X" factor when will help me find the Power, I would need to know at least voltage or watts to figure either one out, Seems I have one unknown here voltage which I don't know where to derive from with just Amperes, not given any electrical resistance because this function is not modelling or was given said diagram

I do believe there is a missing unknown, that is needed to solve for power in terms of watts? Can anyone confirm this?

The thread has had a lot of views. The reason no one has answered is because it it really hard to know what you are talking about just from this post.

I looked at the thread you referred back to (note: *I* had to search for it)...
