The barrier potential of an operational diode can never be made zero. The potential barrier of an operational diode can never disappear. What is a pn junction ? A pn junction allows current in one direction only. It blocks current in the reverse direction. When a pn junction is formed, a potential barrier designated Vo comes into existence and is typically around 0.6 to 0.7 volts for silicon junctions. When the barrier whose Vo is 0.7 volts is disturbed by applying a forward bias of say, 0.6 volts, the current increases and the increase becomes steep for small increments of the forward bias value a little greater than 0.68 volts. Large currents are observed when the forward bias is 0.69 volts which is closer to the barrier voltage of 0.7 volts. The forward bias can never exceed the potential barrier voltage nor can it bring the barrier down to zero volts. That is the reason you seldom see current vs volt graphs of pn junction diodes beyond a volt or so. How does the bias remain less than the barrier in an operational diode? The voltage bias applied drops in the bulk neutral regions of the diode. A detailed description of the pn junction with a distinct approach using surface charges, alignment of Fermi levels, creation of the barrier, the distinct processes of diffusion, drift, recombination and the influence of the electric field on the energies of electrons is provided in the following textbooks.

English ki bhutni India me rahti h yaa out of country rehti h India valo ka yahi problem h sabhi jagah English ka hi use krte h apni rashtra bhasha lupt ho jaegi is English ki vajah se or India kaa bhi rashtra bhasha 5-6 year me hindi ki jagah English ho jaega sale angrez chale gaye but English chhod gaye iska meaning to yahi h ki abhi abhi hum unke gulam hi h sabhi jagah India me English ki jagah Hindi ka use hona chahie . Japan, chaina ki tarah apni matru bhasha ki use karna chahie kehna to nhi chahie but India valo ko copy marna hi ata h. Or Didi app yaha Tak app padh rhi to apko agar naa samaj aya ho to English me bhi explain kru😒

Great explanation, thanks a lot
Waoo mam love the way you say😍😍😍
,very useful 😃😃👍.thnku
Mam ur lessons are very very excellent so medam pls prepare all basics of eee branch pls medam garu
Smart presentation
In forward biasing you didn't even mention immobile ions???
nice ,important theory in electrician ,mast iske objective question bhi kraiye ,kyoki Maine dmrc paper diya tha objective bhout kam pakraye
SCR or V cuerv per video kab banega medam
Best video madam👌👌
please make one on hysteresis losses.
in transformers
Mam I have a request to you kindly provide a video about commutation
Comuutation toh armature mai hota h
Microcontroller per software kaise kiya jata h plz

Good video
Very good mam
Thank you so much mam
Thank you ma'am
Plz make a vedio on embedded technology for doing customise programming
Nyc vedio
i love you roshni
mere ghar andhera rehta h
mujhe roshni ki shakt jaroorat h💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝💝
Nice mam
Hi roshni..
Response to the comments to increase the rate of views
Nice
English ki bhutni India me rahti h yaa out of country rehti h India valo ka yahi problem h sabhi jagah English ka hi use krte h apni rashtra bhasha lupt ho jaegi is English ki vajah se or India kaa bhi rashtra bhasha 5-6 year me hindi ki jagah English ho jaega sale angrez chale gaye but English chhod gaye iska meaning to yahi h ki abhi abhi hum unke gulam hi h sabhi jagah India me English ki jagah Hindi ka use hona chahie . Japan, chaina ki tarah apni matru bhasha ki use karna chahie kehna to nhi chahie but India valo ko copy marna hi ata h. Or Didi app yaha Tak app padh rhi to apko agar naa samaj aya ho to English me bhi explain kru😒
Ye video hindi me chahiye mem
thanks mam
Thanks mem
Thank u mam
Hello

Delcias🎉
Hindi mei chahiye ,Please madam
It would have been easier to understand if you used hinglish
hindi m
Very god
Why do all these videos have to have hard to understand Indian accents
Nice
