This text is meant to accompany class discussions. It is not everything there is to know about the basics of torque and the two conditions of equilibrium. It is meant as a prep for class. More detailed notes and examples are given in the class notes, presentations, and demonstrations (click here.)

 Typically, there are four things that need to be done in a large compound circuit. Reduce the circuit down to a single capacitor. Calculate the potential difference across each capacitor. Calculate the charge on each capacitor. Calculate the energy stored in a circuit or individual capacitor. All of this is shown in the 3 sections below.

Reducing Compound Capacitor Circuits

This video shows how to reduce a compound circuit down to a single, equivalent capacitor. Tis is sometimes refereed to as the total resistance of the circuit.

Finding the Energy Stored in a Circuit of Capacitors

Tis is a continuation of the video above. It shows how to calculate the energy stored in a circuit.

Finding the Potential Differences and Charges

This is the 3rd and final part of the trilogy showing how to find the potential difference across each capacitor and the charge on each individual capacitor in a circuit.
