Generate Bode Plot in LTspice of RLC circuit

In this tutorial, we explain how to generate a Bode plot of an RLC circuit (resistor-inductor-capacitor circuit) in LTspice. We explain how to validate the simulation results by using the second-order system dynamics. The YouTube tutorial is given below.

The circuit is given below.

The simulation is given below.

The formulas for validating the simulation results is shown below.
