1) What is the pattern for how voltage gets distributed in a series circuit with equal resistances? what about with unequal resistances?
2) What about in a parallel circuit for equal resistances? with unequal resistances?
In either scenario, is there any relation btwn the size of resistance and size of voltage?

Apparently you are interested in V=I*R, and the sum of the voltages in a loop are 0. Likewise the sum of the currents into a node are equal to the sum of the currents out of a node.

The rest of your question then is determining equivalent resistances, which follow from these 3 principles.

Thanks, but I'm still not sure I understand how that'll affect the pattern... does that mean there will be negative voltages so the sum is 0? I imagine with equal resistances, voltage would be equal both for parallel and series, but I'm not sure...

If you have current you have a voltage source. Your loop is a complete circuit.

For equal resistances then your current being the same in series will result in what ... ?
