Rank the circuits based on the current through the battery immediately after the switch is closed.
Rank from largest to smallest. To rank items as equivalent, overlap them.
- none given but i=(E/R(1-e^-(R/L)t))
is the equation I found in the book for the current through an LR-circuit. The problem is I cant find anything in the text I have that deals with resistors in series vs parallel, if a coil acts as a short, etc. So can I ask you...
1) is this equation valid for both resistors in parallel and series?
2) If I have a set up like the second and third from the left will the current go through the coil like a short circuit or does the coil have a resistance?
3) in a situation like the second from the right, I can use this equation with the total resistance of the branch and the inductance of the coil? Or does the order matter and if so why?
Are there any concepts I'm missing that I need to analyze an RC circuit?
Thank you for your help.
