N

NEGATIVE ELECTRODE

A terminal or electrode having more electrons than normal. Electrons flow
out of the negative terminal of a voltage source [1].


NEGATIVE FEEDBACK

Feedback in which the feedback signal is out of phase with the input signal.
Also called DEGENERATIVE FEEDBACK [8].


NEGATIVE LOGIC

The form of logic in which the more positive voltage level represents a logic 0,
FALSE, or LOW and the more negative voltage represents a logic 1, TRUE, or HIGH [13].


NEGATIVE TEMPERATURE COEFFICIENT

A characteristic of a semiconductor material, such as silver sulfide, in which resistance to electrical current flow decreases as temperature increases [1] [4]
[7].


NEGATIVE-RESISTANCE ELEMENT

A component having an operating region in which an increase in the applied voltage increases the resistance and produces a proportional decrease in current. Examples include tunnel diodes and silicon unijunction transistors [11].


NETWORK

A combination of electrical components. In a parallel circuit it is composed of two or more branches [1].


NEUTRAL

(1) In a normal condition, hence neither positive nor negative. A neutral object has a normal number of electrons (the same number as protons) [1]. (2) The teletypewriter operation where current flow represents a mark and no flow represents a space [17].


NEUTRALIZATION

The process of counteracting or "neutralizing" the effects of interelectrode
capacitance [8].


NEWTON'S SECOND LAW OF MOTION

If an unbalanced outside force acts on a body, the resulting acceleration is directly proportional to the magnitude of the force, is in the direction of the force, and is inversely proportional to the mass of the body [15].


NO-LOAD CONDITION

The condition that exists when an electrical source or secondary of a
transformer is operated without an electrical load [2].
