Impedance in Series and Parallel
concept
If your circuit has more than one element in it you're going to need a way to combine all their impedances into one equivalent impedance (just like combining resistors in DC circuits).
This topic will cover how to simplify impedances when they're in series or parallel.
fact
Two impedances in series are combined by adding together, just like resistances
example
Simplify the circuit below:
fact
Two impedances in parallel are combined just like two resistances in parallel, using the following formulas:
\(Z_1 \parallel Z_2 = \frac{Z_1Z_2}{Z_1+Z_2}\)
\(Z_1 \parallel Z_2 = \frac{1}{\frac{1}{Z_1}+\frac{1}{Z_2}}\)
example
Find the equivalent impedance of the following circuit section:
