About this Simulation

This interactive simulation models a capacitor connected to a battery, allowing learners to observe how charge accumulates on capacitor plates, how electric fields develop between them, and how voltage, capacitance, and stored energy relate to one another. Adjust plate separation, capacitance, and battery voltage to see real-time effects on charge distribution and field strength.

Learning objectives: Understand the relationship between charge, voltage, and capacitance (Q = CV) | Visualise how electric fields form between capacitor plates and depend on plate separation | Explore how energy is stored in a capacitor and varies with capacitance and applied voltage
