Is relay active or passive?
diode is a two terminal passive non linear device.
Is relay an active or passive device?
Yes, it is an electrically operated switch.
What device is a fuse?
A fuse is a passive device with a conductor that melts when it gets too hot due to the lack of resistance from the load on the circuit.
What is a directional compass?
a compass is a directional object made by the magnetic forces of the earth
What are the three patterns of of natural selection?
directional selection,stabilizing selection, anddisruptiveselection
What is the purpose of a directional coupler?
A directional coupler is a passive device used in radio technology. The purpose of a directional coupler is to couple electromagnetic power to be used in another circuit.
Does a 24db directional coupler or a small 3db inline connector boost a catv signal?
They must be powered to boost the signal. If they are not powered they are "passive" and will consume some of the signal.
How does the directional coupler work in mobile you tube video?
the sim
What is an acoustic coupler?
An acoustic coupler is an interface device for coupling electrical signals by acoustical means.
A potentiometer is a active device or passive device?
passive
What are the different applications of directional coupler?
unidirectional wave length unidirectional power measurement reflectometer balanced duplexer swr measurement
What is passive device?
A passive device is a component that does not require power to operate. A lightning arrester on high voltage lines would fall into this category.
Is relay active or passive?
diode is a two terminal passive non linear device.
Which device is used as a passive hub?
a switch
Is a stop sign a traffic control device?
Yes, it is classified as a 'passive' device.
Why is an inductor called as passive device where as a resistor is called active device?
They are both passive devices. An active device is a device that uses semiconductors (or tubes) to process signals instead of using the natural processes of capacitance, inductance or resistance.
Why non directional relays are connected in sending end of transmission line?
relay:sensing device
