Description
fluxLinkage = inductance*current; differentialInductance = inductance.
Capacitors and inductors store energy under voltage and current conventions, respectively. An ideal endpoint energy difference, charge balance or flux-linkage balance does not determine the transient path or how energy is dissipated.
fluxLinkage = inductance*current; differentialInductance = inductance.
When to use this tool
Use Inductor Flux Linkage Current Point when checking one ideal storage-state comparison or supplied balance.
How to use the tool and how it works
- Enter inductance, current. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read fluxLinkage, differentialInductance. Use the output convention below.
Require nonnegative inductance. fluxLinkage = inductance*current; differentialInductance = inductance.1

| current | Signed electric current; use amperes with SI electrical inputs. | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| fluxLinkage | Flux Linkage | Required. Finite number. |
| differentialInductance | Differential Inductance | Required. Finite number. |

}Limitations and assumptions
- With H and A, linkage is Wb-turns. This assumes constant linear inductance, not a measured nonlinear flux-current curve or saturation model.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use a complete switching and loss model, with component limits, when analyzing practical connections or energy transfer.
