Description
finalVoltage is their capacitance-weighted initial voltage; dissipatedEnergy = 0.5*C1*C2/(C1+C2)*(firstVoltage-secondVoltage)².
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.
finalVoltage is their capacitance-weighted initial voltage; dissipatedEnergy = 0.5*C1*C2/(C1+C2)*(firstVoltage-secondVoltage)².
When to use this tool
Use Capacitor Charge Sharing Dissipation when checking one ideal storage-state comparison or supplied balance.
How to use the tool and how it works
- Enter firstCapacitance, secondCapacitance, firstVoltage, secondVoltage. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read dissipatedEnergy, finalVoltage. Use the output convention below.
Require positive firstCapacitance and secondCapacitance. finalVoltage is their capacitance-weighted initial voltage; dissipatedEnergy = 0.5*C1*C2/(C1+C2)*(firstVoltage-secondVoltage)².1

}Limitations and assumptions
- Use matching voltage polarity and capacitance units. This ideal charge-sharing loss does not resolve where energy is dissipated, connection transients or safe switching.
- 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.
