How it works
Use capacitor energy with the units stated beside the fields. This form solves for voltage magnitude; enter the known quantities in Energy, Capacitance.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Energy | 0.000027 J | Formula symbol: E. Required unit: J. Must be greater than zero. |
| Capacitance | 0.0000015 F | Formula symbol: C. Required unit: F. Must be greater than zero. |

Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
When can I use the voltage magnitude result?
This model uses positive magnitudes. Stored energy of an ideal linear capacitor; use farads and volts.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
