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.
See my real-world example of how parallel resistances
in water flow behave like parallel resistances in electrical circuits.
