Transresistance

Part of speech: noun

Definitions

1. The ratio of voltage change to current change in a transistor, describing how strongly its output responds to an input signal
2. A measure in electronics that expresses how a transistor's output voltage shifts relative to its input current under given conditions
3. The effective resistance a transistor presents when its input current controls the voltage across its output terminals

Etymology: "Transresistance" is a plain technical compound, built from "trans-", a Latin prefix meaning "across" or "through," and "resistance," which descends from Latin "resistere," "to stand back against." Its own parent term is "transfer resistance," a phrase in which "transfer" carries the sense of passing a signal from one place to another. The noun names a quantity in electronics: the ratio of a change in output voltage to the change in input current that caused it, so it treats the device as a kind of resistor that carries a signal across from input to output rather than dissipating it in place.
