Click For Summary
Zener breakdown allows reverse current to flow through a Zener diode, which is often used for voltage regulation. It is possible to power devices using this reverse current, provided the Zener diode is rated to handle the power dissipation without damage. The discussion emphasizes the importance of ensuring the Zener diode's power rating is sufficient for the application. Clarification is sought on whether the inquiry pertains specifically to Zener diodes or another type of semiconductor device. Proper understanding of the circuit configuration is crucial to avoid potential damage to appliances.

Can I power things even after Zener breakdown?
I understand that Zener Breakdown occurs when the reverse current starts flowing in the junction because of which depletion region entirely vanishes. Can I power things using this reverse current ? Or will it damage the appliance?

Can you be more detailed in what you are asking, and post some schematics?

Zener diodes are usually used in shunt configurations, to provide crude voltage regulation. You can use them in series with a load if you want to drop some voltage (the Zener voltage) between your voltage source and the load. Your Zener diode needs to have a power rating sufficient to handle the ##I_s V_z## (series current * Zener voltage) power dissipation, of course.
 
I am referring to reverse current in zener breakdown. I am referring to this part.

Of course. That's how a Zener diode works.

Image link is not working for me. Maybe just paste in the image into a reply? (You'll need to be sure the little Edit icons are not red, but clicking the "[ ]" toggle BB icon if needed)

Or are you not referring to a Zener diode, and are referring to some other semiconductor device?
 
Thread 'Correct statement about size of wire to produce larger extension'

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
