Find the equivalent resistance in the circuit below:

Homework Equations



The Attempt at a Solution



I know the two 4 Ohm resistors (on the same wire) are in series and thus add to 8 Ohms. However, I do not know where to go from here. When the resistors are in a box, with one on each side, are they in series? Or are they two parallels?

Thanks!

I believe the 2,4,2 ohm resistors are all in series since the same current flows through them.

So this would leave me with two parallel resistors of 8 Ohms each? And finding the equivalent resistance would give us 4 Ohms?

If you (or someone else) can confirm this, it would be greatly appreciated!

yep. 8 ohm 8ohm are in parrellel giving 4 ohm net resistance. can be veryfied using kirhoff's law to show current in both branches are the same.
