Read through the class slides. They explain all of the concepts from the module.
Do the Concept Questions first to make sure you understand the main concepts from this module. Then, when you are ready, try the Challenge Problems.
Watch the Problem Solving Help videos for insights on how to approach and solve problems related to the concepts in this module.
The plates of a parallel plate capacitor are a distance d apart. The plates have an area A. Calculate the capacitance of this capacitor.
A circuit contains capacitors in series and in parallel. Find the charge on each capacitor and potential difference across each capacitor.
A spherical capacitor is formed from a solid metallic sphere of radius R1 surrounded by a spherical conducting shell of radius R2. Find the capacitance of this arrangement.
A parallel plate capacitor begins with a distance between the plates of d1. If there is no battery in the circuit, what happens to the potential between the plates when we decrease d1 to d2, with d2 < d1? What happens to the energy stored in the capacitor when this transition takes place? Now, connect the capacitor to a battery. Answer the same questions for this situation as you did for the previous case.
