A diode will only conduct electricity if the polarity of the current is in the correct direction, because diodes can only conduct in one direction.

What is the purpose of the diode inside the relay?
If it is a light emitting diode it is there to let you know that the relay is energized. In my experience, when a DC current is removed from a coil, the polarity of the magnetic field reverses and if it weren't for the diode, the relay would "chatter". The diode polarity is oppsite of the actuating voltage.
Can Crystal Diode acts as a Automatic Switch?
A diode typically has low resistance for current in one direction, and high resistance for current in the other direction. This is not really the description of anything that could be called a 'switch'.
What does diode do?
A diode is a semiconductor meaning it will conduct from anode to cathode if the anode is held positive. Reversing the polarity Will in effect block current flow.
What is a device made of semiconductor material that acts like a switch controlling the flow of electrons in a chip?
if a diode is in forward biased the diode acts as switch is on and when we apply the diode in reverse biased then it work as the switch as off.
What is Transit time in transistor or diode?
A transistor is a switch. A diode directs the flow of current.
Does a diode have polarity?
Yes, a diode inherently has polarity, as current is only allowed to flow one direction.
How do you identify the polarity of a diode when the tester is on diode scale?
To my own understanding, you will use multi-meter to test for the polarity
When diode is connected to ohmmeter What happens?
A: Depends on meter leads voltage polarity and the diode itself orientation to these polarity. One way is should show a low impedance + to anode Reverse the diode it should be hi impedance

What is use of diode?
Diode is a two terminal semicon. Diode is a Switching device
Does a zener diode acts as a switch?
A zener diode cannot be used as switch.
Can diode work as switch?
yes diode can be used as a switch as it conducts current in only one direction.it is a open switch when it reverse biased.and as aclosed switch when it is forward biased.but we consider diode as ideal .
What is unilateral element?
When an element polarity of voltage or current source changes, the magnitude of the corresponding current or voltage changes is called unilateral element. Eg: Diode Even Diode connected back to back in parallel act as a Bilateral.
Can Crystal Diode acts as a Automatic Switch?
A diode typically has low resistance for current in one direction, and high resistance for current in the other direction. This is not really the description of anything that could be called a 'switch'.
What is similar to diode operation?
switch is similar to diode action
