Spanningintensiteitsfactor

Spanningintensiteitsfactor is a Dutch term that translates roughly to “voltage–current intensity factor.” It is not a universally standardized term in electrical engineering or physics; its exact meaning depends on the context in which it is used. In many cases it is used to describe a parameter that links applied voltage to the resulting current or signal intensity, and it is often interpreted in relation to well-known concepts such as transconductance, impedance, or responsivity.

One common interpretation is that the spanningintensiteitsfactor represents a voltage-to-current gain, analogous to transconductance. In this sense, it corresponds to the small-signal slope dI/dV at a given operating point, with units of siemens (A/V). This reflects how sensitively the current responds to changes in voltage, and it is particularly relevant for active devices like transistors where voltage controls current.

A second interpretation treats the factor as an impedance-like ratio, V/I, at a specific operating point, yielding a unit of ohms. This static ratio describes the device’s resistance or dynamic impedance under the measurement conditions and can be useful for characterizing nonlinear or nonlinearized behavior.

In optoelectronic or sensor applications the term may be used more loosely to denote how voltage influences emitted or detected intensity, relating to concepts such as responsivity or electro-optical efficiency.

Measurement typically involves obtaining characteristic curves by varying voltage and recording current (or intensity) to determine the relevant slope or ratio in the linear region of operation, while accounting for temperature, aging, and device nonlinearity.
