Which diode will work when two different diodes are in parallel?

the path of least Resistance
electricity is like water it flows in the direction of least Resistance
so current should flow in the diode with the lowest Resistance
but if the draw on current was high enough it would also start to flow in the higher resistance diode

How transistor work as a diode?
A: Actually a transistor have two diode with the base mas a common terminal. the characteristics of these tow diodes however are not the same as a common diode
What is a special quality of zener diode?
it can work in reverse bias unlike other diodes
How does a zener diode work in forward bias?
Like a normal diode............. unless it includes a "back biased" diode to prevent conduction in this mode as is common in zener diodes rated at about 10 volts or more, then it acts as an open circuit.
Will bad diodes work?
A failed diode electrically resembles a switch. Whether it resembles an open switch or a closed one depends on the specific mode in which it failed. But a bad diode won't behave like a diode any more.
Can diode work on ac power supply?
diodes conduct electricity in only one direction but as ac change direction in each of its cycle diodes can only conduct half of its cycle which will give u a pulsating dc. but if dc is mixed with ac and if it can put whole of its cycle in positive direction diode can conduct ac. so diodes are usually used to produce dc from ac.
Why do diodes have to be placed in a circuit the right way around?
A diode only allows current flow in one direction, so if installed backwards it will not work as intended.
How does the selenium diode work?
Selenium diodes work much like any other diode. They allow current to flow in a forward direction and block current from flowing in the opposite direction. They have a higher forward bias voltage then silicon and as such generate much more heat then a comparable silicon diode. Most selenium diodes will therefore have an integrated heat sink that helps to dissipate all the heat generated. As a zener diode, selenium is used in surge suppression where its heat sink helps in survivability during a surge. However, its low alpha (measure of nonlinearity) means that the voltage during a surge is very high and usually unsuitable to be used as protective device without other components in parallel. The reverse voltage is about 26 Volts, so to get higher voltage zener diode, many are placed in series. By connecting them back to back, then a bidirectionial zener diode can be created. Selenium diode were very common in the 1950s and can be seen in industrial applications of the time. Some model train power supplies were seen to use these components. Since the advent of silicon diodes and their more efficient operation, these part have disappeared from use.
How does a quenching diode work?
Quenching diodes are used to protect the control circuit of a relay. Power is applied to a relay's coil to close it. When this power is released there is a backwards flowing pulse that can wipe out solid state devices like transistors, LEDs, chips, etc... The quenching diode is applied in parallel with the relay coil so that the cathode is on the positive side. During normal operation, the diode doesn't conduct and the relay operates normally. When the relay is switched off, the "reversed" back pulse is absorbed due to the low voltage drop of the diode which limits the spike.
If you were to swap the polarities of a diode would this circuit still operate Elaborate on your answer.?
It isn't clear what circuit you are talking about - and not even what sort of diode you are talking about. But in general, a diode might NOT work the same if you swap the polarity. For instance, a common diode is the rectifier diode; this one lets current through in one direction, but not in the other.Some diodes may even burn out if you connect them with the wrong polarity (and don't have adequate protection in place).
Where gunn diode is used?
Gunn diodes are used in GUNN oscillator over high frequency application. its work on the transfer electron effect TET and the scientist J.B Gunn observe it so the phenomenon is named by gunn effect. the diode are made from GaAs material.because silicon is not suitable low forbidden energy gap 1.21eV only.
What is a ordinary diode?
A diode is an electronic component that will only allow current to flow through it in one direction. It is analogous to the valve in a bicycle tyre, which only lets air in but not out (except when you press the release tab). So if you connect a diode in a simple DC circuit one way around, the circuit will be closed and any devices on the circuit will work. If you connect it the other way around the circuit is open and no current will flow. I presume by 'ordinary diode' you mean a diode that is not a light emitting diode (LED). A LED is just a diode that emits light when current flows through it. Its purpose is to make light. A non-LED diode doesn't emit light. Its purpose is to allow current through a circuit in only one direction. A common use for ordinary diodes is in "rectifying circuits" which convert AC to DC.There are many other uses though.
Diode will work on zero bias or not?
diode does not work on zero bias
