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.
passive
a switch
Yes, it is classified as a 'passive' 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.
A: The difference is PASSIVE / ACTIVE
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.
Yes, a directional coupler is a passive device that is used to split or combine signals in RF and microwave applications. It does not require any external power source for its operation.
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)
Yes, it is an electrically operated switch.
In electronics any device that just pass along a signal by its characteristics is defined as passive.
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.
