Energy stored in a capacitor
Calculate ideal stored energy from capacitance and voltage across a capacitor.
Method and scope
U = ½CV².
Use energy stored in a capacitor for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Capacitance — F, mF, µF, nF
- Voltage across capacitor — V, mV, kV
SOURCE AND LIMITS
Assumptions: Voltage is the potential difference across an ideal capacitor. The capacitor is treated as linear with constant capacitance.
Limitations: Stored energy is not the same as deliverable energy in a real circuit.
