Engineering calculator
Capacitor Energy Calculator
Calculate the electrostatic energy stored in a capacitor from capacitance, voltage, and charge data.
Formula
Q = C·V, U = ½·C·V² = ½·Q·V = Q² / (2C)
Source / method note
Energy calculations are based on an ideal lumped-element capacitor model and fundamental electrostatic equations (U = ½CV²).
Legal / official rate note
These calculations are for educational and design purposes. The tool does not verify safe operating voltages; always adhere to hardware limits.
