Find the equivalent resistance between terminals A and B for this circuit:
I know how to add resistances in parralell and series, it's just that i can't figure out which ones are connected in parralell and which ones are in series
The Attempt at a Solution
It kind of appears that the 20 ohm and 30 ohm resistors are in series, and that 60 ohm and 40 ohm resistors are in series.
But i have no idea.
A parralell connection is one which has both ends of an element directly connected to another. This appears to be true for the 20 and 30 ohm resistors. And also for the 60 and 40 ohm resistors. But where in the circuit would i place their equivlent resistances?
So i guess the question i'm asking is more to do with how to identify which ones are parralell and which ones are in series
