Hello forum, please see the attached image.

This problem amounts to finding the equivalent resistance for the circuit and using Ohm's law to solve for the current.

2. Relevant equations

V=IR

3. The attempt at a solution

What I really need help with is learning how to recognize series and parallel combinations in complicated circuits like this one. It's difficult for me to see any possible combination, series or parallel, in this circuit. It looks to me that if you follow the current down from the top of the resistors, that the first three are definitely parallel, but then those are also in parallel with the others so I really don't see how you're supposed to combine them.
