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.

Sheet resistance (Ω/□)

Required number input.

Current-path length (mm)

Required number input.

Electrode width (mm)

Required number input.

Estimate end-to-end resistance of a uniform rectangular resistive touch layer with electrodes across its full width. 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]

Layer resistance (Ω)

The resulting layer resistance 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.

• Thevenin Resistance

  Compute the Thevenin resistance in ohms of a resistive divider seen from its output.

• ADC LSB Voltage

  Calculate one ideal ADC code width as full-scale input span divided by 2^N. Full-scale span is the high-to-low range, not necessarily the reference voltage for every ADC topology.

• Short Dipole Rrad

  Compute the radiation resistance of a short dipole from its length and wavelength using Rrad = 80 x pi^2 x (l/lambda)^2.
