i know this, but never mind the question, how do i differentiate between a series and a parallel circuit? going back to the question, all the resistors are "parallel" to each other so how can i tell?
will the SAT Physics test ask me something like "What does the Second Law of Thermodynamics say should happen..."? If so, do I need to memorize all these laws? How can I possibly know them all? Is there a list?
so that means i add the 2R and the R to get 3R, hence V/3R, and that the right side is a series circuit? why is it a series circuit if they are parallel to each other? yet the 1/2 R's on the left side are treated as parallel?
