E&M - Circuit Analysis

In 4 Chem-Phys, we are looking at circuit analysis for resistor circuits.  We have our rules: Ohm's law, V = IR; Series and Parallel resistances (add in series, add reciprocals in parallel and flip over); and Kirchhoff's 2 rules (in series voltages add to that of the battery, in parallel the currents add to the total).  A video for applying all this is here.
