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.

Conductance (S)

Required number input.

Susceptance (S)

Required number input.

Calculate the magnitude of admittance from conductance and susceptance. 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]

Admittance magnitude (S)

The resulting admittance magnitude returned as a number.

• Compact electronics formulas omit some combination of tolerances, temperature drift, bandwidth, loading, parasitics, noise spectrum, nonlinearity, clipping, calibration, layout, and device-specific limits. Typical datasheet values are not guaranteed limits.
• 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.

• Ac Motor Reactive Power

  Calculate positive reactive-power magnitude for a balanced three-phase motor from line voltage, line current, and power factor.

• Ideal Capacitor Impedance

  Calculate ideal capacitive reactance Xc=−1/(2πfC) and its magnitude in ohms. ESR, ESL, leakage, and self-resonance are not included.

• Complex Power Magnitude

  Calculate the magnitude of complex power from real and reactive power.
