Definition for Capacitance

The quality of an electronic circuit that exhibits an impedanceDefinition:
Also abbreviated as Z. The resistance to AC current flow, measured in ohms (similar to, but not necessarily, the same as DC resistance). to ACDefinition:
AC (Alternating Current): Current whose electrical flow alternates between positive and negative quadrants, and whose magnitude varies periodically. Alternating current is used in most commercial power transmission, and is also the basis of audio or video signals. signals, so that as the frequencyDefinition:
A value, expressed in Hertz, that indicates how many cycles of a periodic signal occur in one second. of the input signal increases, the capacitance exhibits a decreasing impedance to that signal.
