So i have a general question that I came across with source transformations, but this question can be classed as a beginner question.

When I find the equivalent resistance, how do you determine whether or not it is in series or parallel with a source?
 
Physics news on Phys.org
when the resistors have equal voltage then they are in parallel. and when they have equal current then they are in series :)
 
umm can you explain a little more, I don't understand.
 
I don't understand how I could use that to determine whether or not my equivalent resistance is in parallel or series with sources
 
Your question doesn't make much sense. "Equivalent resistance" can be either in series or in parallel with a voltage source, depending on what equivalent resistance you're talking about in a circuit.
 
Sorry, can you look at this question http://www.cramster.com/solution/solution/727803
if you look at the 10 and 40 ohm resistor, why is it when you find their equivalent resistance, they are in series after.

oh k nvm i got it thnx.
 
When resistors share the same nodes they are in parallel, when they only share one common node (with no other resistances nodes sharing that common node) they are in series.
