types:
bus,
busbar
an electrical conductor that makes a common connection between several circuits
electrode
a conductor used to make electrical contact with some part of a circuit
heat sink
a metal conductor specially designed to conduct (and radiate) heat
lightning conductor,
lightning rod
a metallic conductor that is attached to a high point and leads to the ground; protects the building from destruction by lightning
wave guide,
waveguide
a hollow metal conductor that provides a path to guide microwaves; used in radar
anode
a positively charged electrode by which electrons leave an electrical device
base
(electronics) the part of a transistor that separates the emitter from the collector
cathode
a negatively charged electrode that is the source of electrons entering an electrical device
collector
the electrode in a transistor through which a primary flow of carriers leaves the region between the electrodes
electrical cable
a cable that provides an electrical connection for telephone or television or power stations
electron gun
the electrode that is the source of electrons in a cathode-ray tube or electron microscope; consists of a cathode that emits a stream of electrons and the electrostatic or electromagnetic apparatus that focuses it
emitter
the electrode in a transistor where electrons originate
extension cord
an electric cord used to extend the length of a power cord
filament
a thin wire (usually tungsten) that is heated white hot by the passage of an electric current
control grid,
grid
an electrode placed between the cathode and anode of a vacuum tube to control the flow of electrons through the tube
lead-in
wire connecting an antenna to a receiver or a transmitter to a transmission line
n-type semiconductor
a semiconductor in which electrical conduction is due chiefly to the movement of electrons
patchcord
a length of wire that has a plug at each end; used to make connections at a patchboard
power cord
a cord to conduct power to an electrical appliance
p-type semiconductor
a semiconductor in which electrical conduction is due chiefly to the movement of positive holes
thermal resistor,
thermistor
a semiconductor device made of materials whose resistance varies as a function of temperature; can be used to compensate for temperature variation in other components of a circuit
