H: Series-Parallel Capacitors - Collapse-Expand Bookmark this page You are given three initially discharged capacitors, C₁, C₂, and C3. You wire the capacitors in a series-parallel circuit as shown, where C₂ and C3 are wired in parallel and that parallel combination is then wired in series with capacitor C₁. The combination is connected to a battery of voltage V, producing the capacitor voltages V₁, V₂, and V3 and charges Q1, Q2, and Q3. The goal is to apply the collapse-expand method to solve for the capacitor charges, voltages, and stored energies.
