Formula and methodology
Formula: Energy = 0.5 C V^2; charge = C V.
This ideal capacitor relation gives stored electrostatic energy and charge from capacitance and voltage. Reversing voltage polarity changes charge direction but not the reported energy.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Capacitance — F; minimum 1.0E-15; maximum 1000000
- Voltage magnitude — V; Enter a nonnegative voltage magnitude.; minimum 0; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Capacitance | 1.0E-6 |
| Voltage magnitude | 12 |
Stored energy is 0.000072 J and charge is 0.000012 C.
Assumptions and limits
- Capacitance is constant and entered in farads.
- Voltage is a nonnegative magnitude in volts.
- Leakage, dielectric loss, voltage rating, ESR, and discharge safety are not modeled.
