Why mostly a transister is used as amplifier than diode?
A diode is not an amplifier. It is a rectifier with asymmetrical voltage breakdown voltages. Usually the forward voltage is around 0.6V to 0.7V (silicon), and the reverse voltage is smaller than breakdown voltage, which is much higher. A transistor can be used as an amplifier, by taking into account the fact that the voltage breakdown curves vary, usually collector-emitter, as a function of some other current, usually base-emitter, but this depends on the class of the amplifier and whether or not the transistor is driven into saturation.
Why is the rectifier diode never operated in the breakdown region?

What is the use of finding the bandwidth of an amplifier?
A: Any amplifier will have greater band with if operated open loop. It will also be very unstable so negative feedback is implemented for that reason. There is some drawback when feedback the band width of the amplifier decreases, So is important to find out if the amplifier when stable will it have the band width required
What type of diode is a HVR-1X4 diode?
It's a high voltage diode, typically used in microwave ovens.
What is the diode and Why it is used in electronic circuits?
A diode is basically a electronic non return valve it let current flow in one direction only and can not be used for amplification it only consist of a cathode and anode, where the transistor can be used in many applications, for instance as an amplifier, electronic switch, oscillator etc. it consist of three connections eg. Collector, Emitter and a Base normally the current is collected at the Collector and emitted at the Emitter and the Base is used to control the current flow with the Base at 0 volt no or very little current will flow between C and E it will only switch on with the B at about 2.7volt and the higher the B voltage the more current will flow thru the transistor
Can an amplifier can be operated on ac supply?
Yes, an amplifier can be operated on ac supply.
Is zener diode a voltage amplifier or currentlimitig circuit or osilator circuit?
The zener diode is neither a voltage amplifier nor a current limiting device but can be used in oscillator circuits to supply a constant output voltage.
What is the use of superdiode?
superdiode consist of diode and amplifier circuit.it is used for the rectification of small signals
Can a pn junction diode be used as an amplifier?
Never. It is impossible to use diodes for amplification.
Why diode can't use as amplifier?
A2. For amplification to take place, one needs three terminals; an input, an output, and a control signal.This indicates the original " valve" naming; after a mechanical valve, where a small effort on a (hydraulic) valve may be used to control a larger effort of the controlled fluid.A1. If u meant why diode can't be used as an amplifier diode is used as a rectifier..it converts ac current to dc and there is an inbuilt voltage drop... so it can't be used as an amplifier
How do you use a diode as temperature sensor?
The voltage across a Silicon Diode junction varies 0.00011 volts per degree Kelvin. Connect the diode to a high gain amplifier and the output of the amplifier to a DVM using an appopriate voltage scale.
What are the system applications of a class B amplifier?
Class B operated amplifier is used extensively for audio amplifiers that require high power outputs. Its also used as the driver and power amplifier stages of transmitters.

Zener diode operates In an extremely high forward bias?
False, a zener diode is normally operated reverse biased in breakdown.

Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
