Term	Explanation
NEC	National Electrical Code
NEMA	National Electric Manufacturers Association
Neoprene	A synthetic rubber with good resistance to oil, chemicals and flame.
	Also called polychloroprene.
NFPA	National Fire Protection Association.
Noise	In a cable or circuit, any extraneous signal which tends to
	intefere with the signal normally present in or passing through
	the system.
NPN	A type of transistor which requires a positive power supply.
Off-Delay	The output signal rises immediately upon the receipt of an input
	signal and is maintained by a preset time after the input signal
	is removed.
Off-State Condition	The condition of a solid-state device where no control signal
	is applied.
Off-State Current	The current that flows in a solid-state device in the off-state
	condition.
Ohm	The electrical unit of resistance. The value of resistance through
	which a potential difference of one volt will maintain a current of
	one ampere.
Ohm's Law	R = Resistance     E = Voltage     I = Ampere
	I = E:R           Ampere =  Voltage : Ohm
	R = E : I         Ohm       =  Voltage : Ampere
	E = R x I         Voltage =  Ohm x Ampere
