A resistance such that when the current through it increases the voltage drop across the resistance decreases.

Property of some specialized circuits by means of which current increases as voltage is decreased.

a two-terminal device having a volt-ampere characteristic with negative slope over the range of voltages or currents wherein it is operative, that is, an increase in voltage results in a decrease in current, or vice versa

The characteristic of a circuit in which current varies inversely with applied voltage.

A device having negative voltage-current characteristics. For a certain value of voltage, a point is reached where a voltage increase causes a current decrease (equivalent to a resistance decrease).

slow eccentric muscle contraction against a resistance.

A term used to describe a region of operation where current and voltage are inversely proportional.

Negative resistance or negative differential resistance (NDR) is a property of electrical circuit elements composed of certain materials in which, over certain voltage ranges, current is a decreasing function of voltage. This range of voltages is known as a negative resistance region.
