Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Breakdown Field (V/m) (V/m)

Required number input.

Gap (m) (m)

Required number input.

Estimate uniform-field gas-gap breakdown voltage as assumed breakdown electric field times electrode separation; real gaps require pressure and geometry data. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Breakdown (V) (V)

The resulting breakdown (v) returned as a number.

• Breakdown voltage depends on gas composition and pressure, gap geometry, electrode material and condition, polarity, humidity, rise time, field uniformity, and statistical delay. Simple gap laws do not define safe insulation clearances.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Motor Power Factor At Load

  Calculate balanced three-phase motor power factor as real input power divided by √3 times line voltage and line current; the result is a magnitude.

• APD Excess Noise Factor

  Calculate electron-injection APD excess noise factor from gain and ionization-rate ratio using the McIntyre uniform-field model.

• Battery Life Calculator

  Estimate battery runtime from rated charge capacity and constant load current: hours = mAh / mA. Real-world derating (Peukert effect, temperature, cutoff voltage) is not modeled.
