A wire that connects two points in a circuit; it is usually self-supporting.
Metaphorically, moving ahead, often but not in
cybernetics, the opposite of
lag. In the
cybernetics of
regulation, lead refers to the ability of a regulator to extrapolate (
see prediction ) the
behavior of the regulated
system (beyond or ahead of available
data ) and act on that future
state of the system which is anticipated to coincide with the arrival of the corrective action. Thus the lead may compensate for the lag involved in a
feedback loop provided and to the extent that the
behavior of the regulated system is predictable. (
