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.

A potentiometer is a active device or passive device?
passive
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.
What difference in electrical and electronic device?
A: The difference is PASSIVE / ACTIVE
What is active devices?
An active device amplifies the signal by some value - such as an active filter using an OPAMP. A passive device does not provide any amplification - such as a passive filter network of inductors and capacitors.
What is the device that produce gain active or passive?
Either. although a passive device can only produce gain from 0-1 (-inf to 0dB) an active device on the other hand is capable of producing gain thats greater than 1 (0dB)
Is relay an active or passive device?
Yes, it is an electrically operated switch.
Is an antenna active device?
In electronics any device that just pass along a signal by its characteristics is defined as passive.
Is diode an active or passive device?
An active device is a device that takes input energy to operate. The only energy a diode uses is from the signal applied to it (it has one input, one output, and no other terminals), so it is a passive device. To be an active device, a separate power source must be applied to it - such as the case for operation amplifiers, for example.
Is resistance a linear device?
YES it is linear. It is a passive device classified as linear however as frequency increases its behavior will change.
