N

N-TYPE - A semi-conductor material that has an excess of free electrons.

NAND GATE - A type of logic device that requires all inputs to be YES in order for the output to be NO.

NEGATIVE POLE - Point from which an electrical current flows as it passes through a circuit.
NO-LOAD TEST - A test for starter motors in which current draw is measured when the starter's pinion gear is not engaged.

NOR GATE - A type of logic circuit that if either input is YES, the output is NO.


NORMALLY CLOSED - Refers to a switch or a solenoid that is closed when no control or force is acting on it.

NORMALLY OPEN - Refers to a switch or solenoid that is open when no control or force is acting on it.

NOT GATE - A type of logic circuit that has an inverted output; if the input is YES, the output is NO, and vice versa.

NPN - A transistor with a P type base sandwiched between an N type emitter and collector.
