A diode itself has no input or output.
The circuit containing the diode usually has an input and an output, maybe even more than one of each. The output of this circuit will depend on far more than the diode as well as depending on the type of diode used.
Theoretically: if a diode is connected across the secondary output of a stimulated transformer, you would read a half wave at the frequency of the source across diode.
Such a circuit would cause any real diode to explode due to lack of any current limiting and the resulting high power dissipation in the diode.
Hence "Theoretical". That's kind of what "Theoretical" means.

What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
What happens with voltage and current by damaged diode...the diode is IN5408?
It depends on how the diode is damaged. There are generally two cases. One, the diode is shorted, and conducts with a low impedance in both directions. The other, the diode is open, and does not conduct, having a high impedance, in both directions. The effect depends on the particular circuit. In a power supply, a shorted diode will often blow the fuse, while an open diode will result in no output, or in high ripple voltage output. Is it possible that diode has normal voltage output but wrong current,meaning low mA?
What is the role of free wheeling diode in ULN2803?
A free wheeling diode is used to suppress or eliminate flyback. In ULN2803, the free wheeling diode protects the output.
What happens to the output when one of the diode becomes open in full wave bridge rectifier?
The output degrades to a half-wave rectifier.
How does a zener diode maintain constant output voltage?
sharp reverse breakdown function
What is the effect of diode voltage drop as the output voltage?

What effect does an open diode have on the output voltage of a half wave rectifier and on a full wave rectifier?
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.
What is the purpose of a zener diode when placed near the output in a common power suplly?
The purpose of a zener diode connected at the output of a common supply is to stabilize the output voltage in case a load is connected to it.
What will happen when a dc source is used in front of a diode in half wave rectifier?
If the DC source biases the diode off, then the output will be zero. If it biases the diode on, then the output will be DC, with the voltage being nearly the same as the input voltage.

Which electrical voltage value does a dmm output when in diode test mode?
When testing a diode with dmm in diode test mode 0.6v is delivered through the device to indicate continuity
What is diode detector?
there are two types:- 1) simple diode detector 2) practical diode detector the diode is common device used in am demodulator. signal(am demodulator signal ) is applied anode and output is taken from cathod
When the diode in an envelope detector rectifies the electrical current how come the output isn't buzzy like when a sine wave has the bottom completely cut out the output sounds buzzy?
because the capacitor connected to the diode on the output side "filters out" the areas that would normally be chopped out by the diode. It does that, for example, by maintaining the voltage during the cut out portion of the sine wave.
What happens to the output when one of the diode becomes open in full wave bridge rectifier?
The output degrades to a half-wave rectifier.
What happens to the load if reverse the polarity of diode?
if you reverse the diode in a half wave rectifier, you would expect the A- Ripple to increase B- output to be less filtered C- out put polarity to be reversed D- output voltage to decrease
Why diode logic gate is not suitable for cascading operation?
the pullup or pull down resistance in the diode logic gate makes it a high output resistance device.If u try to drive another diode logic gate with it the output voltage of the first gate will be affected by the resistance in the second gate.A diode logic gate should always drive a high input resistance input.
