Mutual inductance - Ability of one inductor's lines of force to link with another inductor.

Network - Combination of interconnected components, circuits or systems. (Back to top)

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.

Nickel-cadmium cell - A secondary cell that uses a nickel oxide positive electrode and a cadmium negative electrode.

Node - Junction or branch point in a circuit.

Noise - Unwanted electromagnetic radiation within an electrical or mechanical system.

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.

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.

Nucleus - Core of an atom. The nucleus contains both positive (protons) and neutral (neutrons) subatomic particles.

Ohm - Unit of resistance symbolized by the Greek capital letter omega (W). (Back to top)
