Negative
- negative
-
Terminal that has an excess of electrons.
- negative charge
-
A charge that has more electrons than protons
- negative feedback
-
A feedback signal 180° out of phase with an amplifier input signal. Used to increase amplifier stability, bandwidth and input impedance. Also reduces distortion.
- negative ground
-
A system where the negative terminal of the source is connected to the system's metal chassis.
- negative ion
-
An atom having a greater number of electrons in orbit than there are protons in the nucleus.
- negative resistance
-
A resistance such that when the current through it increases the voltage drop across the resistance decreases.
- negative temperature coefficient
-
A term used to describe a component whose resistance or capacitance decreases when temperature increases.
- neon bulb
-
Glass envelope filled with neon gas which when ionized by an applied voltage will glow red.
- network
-
Combination of interconnected components, circuits or systems.
- neutral
-
A terminal, point or object with balanced charges. Neither positive or negative.
- neutral atom
-
An atom in which the number of negative charges (electrons in orbit) is equal to the number of positive charges (protons in the nucleus).
- neutral wire
-
The conductor of a polyphase circuit or a single-phase three wire circuit that is intended to have a ground potential. The potential difference between the neutral and each of the other conductors are approximately equal in magnitude and equally spaced in phase.
- neutron
-
Subatomic particle in the nucleus of an atom and having no electrical charge.

-
Unwanted electromagnetic radiation within an electrical or mechanical system.
- non-inverting input
-
The terminal on an operational amplifier that is identified by a plus sign.
- non-linear scale
-
A scale in which the divisions are not equally spaced.
- normally closed
-
Designation which states that the contacts of a switch or relay are closed or connected when at rest. When activated, the contacts open or separated.
- normally open
-
Designation which states that the contacts of a switch or relay are normally open or not connected. When activated the contacts close or become connected.
- north pole
-
Pole of a magnet out of which magnetic lines of force are assumed to originate.
- Norton's theorem
-
Any network of voltage sources and resistors can be replaced by a single current source in parallel with a single resistor.
- notch filter
-
A filter which blocks a narrow band of frequencies and passes all frequencies above and below the band.
- NPN
-
Negative-positive-negative
- npn transistor
-
A bipolar junction transistor in which a p-type base element is sandwiched between an n-type emitter and an n-type collector.
- ns

Nanosecond
- n-type semiconductor
-
A semiconductor compound formed by doping an intrinsic semiconductor with a pentavalent element. An n-type material contains an excess of conduction band electrons.
