Parallel RLC Combinations
Here are the most common parallel configurations of resistors (R), inductors (L), and capacitors (C). These are the basic forms, and all other parallel combinations can be reduced to one of the following forms. For instance, if you have three capacitors in parallel with two inductors in parallel with two resistors, you can reduce the parallel resistors to a single equivalent resistor, and the same with capacitors and inductors. You will end up with the Parallel RLC form at the lower left.
