Circuit schematic of a general voltage divider with impedance components Z1 and Z2

The information presented in this blog post is for educational purposes only. It should not be used for engineering design or relied upon as engineering advice.

A previous blog post showed how to analyze a resistive voltage divider. This example expands on the previous example to analyze a voltage divider that consists of any combination of resistors, capacitors, and inductors. The main impact of using capacitors and inductors in a voltage divider is that the gain between the output voltage and the input voltage becomes a function of input frequency. Additionally, the impedances for the components become complex numbers and require using the complex number capabilities of EngineeringPaper.xyz.
