Homework Statement:Rank the circuits based on the present through the battery instantly after the switch is closed.

You are watching: 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 identical, overlap them.Relevant Equations:none given yet i=(E/R(1-e^-(R/L)t)) is the equation I discovered in the book for the present via an LR-circuit. The difficulty is I cant find anypoint in the text I have that faces resistors in series vs parallel, if a coil acts as a short, and so on So deserve to I ask you...1) is this equation valid for both resistors in parallel and series? 2) If I have a set up choose the second and also third from the left will the current go with the coil favor a short circuit or does the coil have actually a resistance?3) in a case choose the second from the appropriate, I can usage this equation through the complete resistance of the branch and the inductance of the coil? Or does the order issue and also if so why?Are there any type of principles I"m absent that I must analyze an RC circuit?Thank you for your assist.

Firstly, if the battery is treated as ideal, definition it has zero internal resistance, then 2 out of the 6 circuits will lead to nonsensical outcomes. This deserve to be avoided by treating the battery as non-right, having actually a small, non-zero inner resistance.I would certainly not worry around the equation for this exercise. The key word is "instantly," in "immediately after the switch is closed."One key element in solving this problem is to answer these 2 questions:(i) Is it possible to instantaneously adjust the voltage throughout the terminals of an inductor?(ii) Is it possible to instantaneously adjust the present through an inductor?
