A passive device disables the vehicle by making the fuel, ignition, or starting system inoperative. A disabling device is classified as passive if a separate manual step is not required to engage the device.
a passive circuit component has no emf. The term comes from the idea that it responds to something done to it by an active device, such as a battery. Light globes and capacitors are passive devices.
A discrete component that is not active, where an active component is one whose operation involves the activity of a semiconductor junction. Resistors and capacitors are examples of passive devices.
A circuit or network not using active devices such as tubes to transistors.
A device that does not have a dedicated supply source and operates solely on the input(s) alone.
A device, such as a splitter, that does not required power to operate. Passive devices have no gain, but do create attenuation in the signal path to which they are inserted.
A device that must draw its current from connected active equipment. A balun, for example, is a passive device.
A device incapable of current gain or switching, such as a resistor or capacitor.
A device used in a cable system not requiring electrical power to operate. It normally represents loss to signals passing through it. Examples of passive devices are splitters, directional couplers, pads, and equalizers.
Any device that does not require a source of energy for its operation. Examples include electrical resistors or capacitors, diodes, optical fiber (photo), cable, wires, glass, lenses, and filters.
