In this video, I use LTSpice to check some calculations I did by hand.
You can see the original video here:
   • Capacitor Charging - Challenging Prac...  
(Capacitor Charging - Challenging Practice Problem)

In that video, I used Thevenin's theorem to determine an equivalent circuit to allow me to determine the equations for a charging capacitor circuit. Here, I confirm the results by simulating the original and the Thevenized circuit side-by-side.
