**General Steps to Solving
Circuits:**

1) Reduce parallel elements to a series equivalent.

2) Determine the total resistance in the circuit.

3) Use Kirchoff's Laws to determine all possible voltages and currents.

4) Use V = IR (Ohm's Law) to determine 3rd quantity whenever two are known.

5) Summarize values in a chart.
