A diode is an electronic component which only allows the current to pass through it in one direction. This is useful in many aplications, such as preventing current to flow in the wrong direction in a circuit.

A resistor is also an electronic component, but instead of preventing the current from moving in a certain direction the resistor creates an electrical resistance which will effect the current passing through it. The larger the resistance of the resistor, which is measured in Ohm, the greater the effect it will have on the current.

Is superposition theorem applicable for diodes?

No, diodes are not linear elements like resistors are. Current can only flow in one direction in diodes.


What was the major effect of replacing the two diodes with resistors?

As I have no information on the circuit I can make no valid predictions as to the effect of replacing diodes with resistors. However I assume the effect(s) will resemble that of having very defective diodes in the circuit.

Why not gate is not possible using diodes?

Diodes cannot invert, a required part of the not operation.


Do diodes have resistance?

Yes, diodes have resistance, but it is typically low compared to other components like resistors. The resistance in a diode is non-linear and varies with the voltage applied across it.


What is the difference between series and parallel diodes?

Connecting diodes in series:Connecting diodes in series will increase the forward voltage of the resultant diode.Connecting diodes in series will cause an open circuit until peak inverse voltage (smallest diode) is applied on total resultant.Connecting diodes in parallel:Connecting diodes in parallel will increase the current carrying capacity of the diode.Connecting diodes in parallel will not get you a resultant diode conduction in both sides.

Difference between zener diode and junction diode?

Zener diodes and ordinary junction diodes are similar, except that zener diodes have additional doping to bring their reverse breakdown voltage into a more usable value, and to allow them to not destructively avalanche when they do conduct in the reverse direction.


What is difference between power diode and ordinary diode?
