INSULATION

A material used to prevent the leakage of electricity from a conductor and to provide mechanical spacing or support as protection against accidental contact with the conductor [1] [4].


INSULATION RESISTANCE

The resistance offered by an insulating material to current leakage [4].

INSULATOR

(1) Material of such low conductivity that the flow of current through it can usually be neglected. (2) A device having high electrical resistance; used for supporting or separating conductors so as to prevent undesired flow of current from the conductors to other objects [1].


INTEGRATED CIRCUIT

(1) A circuit in which many elements are fabricated and interconnected by a single process (into a single chip), as opposed to a "nonintegrated" circuit in which the transistors, diodes, resistors, and other components are fabricated separately and then assembled [7]. (2) Elements inseparably associated and formed on or within a single substrate [14].


INTELLIGENCE

In communications any signal that conveys information (voice, teletypewriter,
facsimile) [17].


INTENSITY

INTENSITY (OF SOUND)—The measurement of the amplitude of sound energy. Generally synonymous with loudness [10].


INTERACTION SPACE

The region in an electron tube where the electrons interact with an alternating
electromagnetic field [11].


INTERCEPT

The point where two lines drawn on a graph cross each other [10].

INTERELECTRODE CAPACITANCE

The capacitance between the electrodes of an electron tube [6] [11].


INTERFERENCE

Any disturbance that produces an undesirable response or degrades a signal [10].
