LEAD (ELECTRONICS)

In electronics, a 'lead' is the technical name for an electrical connection, usually a wire, coming from an electronic device and often connecting to another. Leads are used to transfer power, to probe circuits (see multimeter), and to transmit information. The leads coming off through-hole components are often called "pins".
In electronics, the difference in time between two waveforms of the same frequency. One waveform is said to 'lead' another if it precedes it. (See also Phase (waves), especially the section on "Phase Shift")
