Lesson Plan: Resonance in Alternating Current Circuits Physics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the resonant frequency and 𝑄 value of simple resistive-capacitive-inductive circuits.


Students will be able to

  • use the following equations to calculate resonant circuit frequencies and circuit 𝑄 values: 𝜔=1(𝐿𝐶)resonant and 𝑄=𝜔𝐿𝑅.


Students should already be familiar with

  • the angular frequency of an alternating current, 𝜔=2𝜋𝑓,
  • capacitance,
  • capacitive reactance,
  • inductance,
  • inductive reactance.


Students will not cover

  • parallel circuits.
