In which condition a p-n junction diode works as open switch ?

Under what condition does a p-n junction diode work as an open switch ?

What is a junction diode?

If a p-n junction diode is in reversed bias

If a p-n junction is reverse biased then

When a p-n junction is reverse biased then

What is rectification ? Explain with diagram how a p-n junction diode acts as a half-wave rectifier.

Direction : These question have statement I and statement II. Of the four choices given below choose the one that best describes the two statements. Statement I: The depletion of thermal layer is also generated at the junction of a p-n junction diode without any applied biasing. Statement II. The diffusion of thermal electrons and holes takes place from one region to another.
