Yes, it is an electrically operated switch.
diode is a two terminal passive non linear device.

Active is actually smoking. Passive is standing near active, and breathing in their smoke, indirectly.
diode is a two terminal passive non linear device.
passive
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.
Passive Load is Load comprising of Passive Components Active Load is the Load comprising of Active Components In Test Boards its better to use Active Loads, If you are concerned about Temperature Variations during characterisation
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 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.
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)
It has to have resistors but an active filter will alsol have an active device, usually an op-amp, while a passive filter has only passive components and needs no power supply.
In electronics any device that just pass along a signal by its characteristics is defined as passive.
A; Any components that provide gain/loss are active device resistors, capacitors are passive
An active antenna is an antenna which has an amplifier attached very closely to it. The antenna/amplifier system is called an active antenna. It is used for receiving signals only. The idea is to set the signal-to-noise ratio (SNR) before the signal travels along a transmission line where it is susceptible to interference and loss.
