Capacitance Equations

Open in new tab 🔗

This app is an interactive tool for teaching how capacitors behave when connected in series and parallel. Students can enter values for two or three capacitors and switch between series and parallel arrangements to see how the total capacitance changes. By manipulating the capacitor values and observing the resulting total capacitance and underlying equations, learners build a deeper understanding of the rules for combining capacitors in circuits — such as how in series the total capacitance decreases and in parallel it increases.
