00:07 Ideal diode allows generous flow of current in forward bias but blocks current in reverse bias
00:59 Current through the diode is equal to Is.
02:06 In ideal diode, there is no resistance for the diode current
03:08 In reverse bias, ID is nearly zero, making it ideal. In forward bias, diode acts as a closed mechanical switch due to current flow.
04:11 A semiconductor diode only permits current to flow in one direction.
05:15 The VI characteristics for practical and ideal diodes have been plotted.
06:22 In forward bias condition, voltage across an ideal diode is 0.
07:19 Ideal diode has VD equal to 0 and current through the diode is equal to 0 in reverse bias condition.

thank you

[@nituldas1438]

si please upload OPAMP VIDEO, RELATED TO GATE AND IES XAM, I ALREADY SHOW UR ANALOGS VIDEO, IT REALLY HELPS ME LOT, THE WAY U R TEACHING IS AWESOME, WAITING FOR OPAMP VIDEO , AND FOURIER SERIES , Z TRANSFORN IN SIGNAL N SYTEMS

[@theasteroid00]

you're a better teacher than my professor 🙃

[@umamaheshdevarajula3048]

sir explain about static resistance and dynamic resistance

[@makeitsimple247]

Your all vedios are good but at 2:51 i think nothing can be equal to infinity you should use tends to sign

[@priyankkumargupta9586]

I believe temperature refers to the ambient temperature. Does breakdown voltage changes with load current variations as that may impact the junction temperature?

[@cinnamonshake45]

hows your life after 5 years...

[@ashishashutosh6038]

Hello sir can you make a video of numerical of load line analysis having 2 diodes silicon and germanium in one circuit 😊

[@dalenassar9152]

Are high voltages (several kV) available in ideal diodes??
GREAT VIDEO!!!

[@electronicswithmadhan1052]

Sir practical diode also has Generation and Recombination current, due to that also the graph slightly varies.... Am I right??

[@ramankr0022]

verry helpful

[@ManojKumar-zc3tc]

Thanks sir

[@alfredcalleja450]

Brilliant: thank you.

[@029belekuldeepkumarrajak6]

Why in semiconductor diode current flows only in one direction?

[@i_m_hk]

Excellent 🔥

[@isurumaldeniya105]

since diodes are non-ohmic is it ok to apply ohm's law and calculate those answers for ideal diode?

[@shamaunshamaun5130]

same question also from me.

[@info-hub457]

If vd across a diode is zero in case of forward biasing, how is there any current??

[@smruti6684]

Sir pls reply what is reverse saturation current ...(saturation current) ?

[@shanmukhjashwanthbb5update586]

See previous videos 14

[@hm2715]

In forward bias, current flows but voltage is 0 since resistance is 0 too, how is that possible to have current when voltage is 0?

[@MrAdeelPhysicist]

Because of minority carriers

[@muhammadsoaban5166]

In forward bias we neglected barrier potential, forward dynamic resistance, diode act like open switch so we says that voltage drop across diode is zero bc it's short circuit and current is flowing right

[@kayeannerepatacodo7792]

What application are you using in this video sir?

[@vipultyagi7220]

thanks a lot

[@sercansavci7739]

thx my hero

[@ajaybissa3862]

sir can u provide the notes of these topic on telegram plzzz

[@namrakhan3259]

Sir what is static resistance and dynamic resistance

[@hafsakhalil7458]

Small resistance is called Dynamic resistance

[@sibongakonkengobese3216]

Dynamic resistance is the internal resistance of a diod in a forward condition. It influences the curve of V-I because if the forward voltage is less than barrier voltage the current tends increase gradually, but once it has passed the knee point, which is 0.7 V for diode, the forward current increases rapidly. After 0.7 V the forward dynamic resistance is very small.

[@medizinvonmorgen1217]

awesome, thanks

[@AKDas-or6si]

Why graph shifts left with increase in temperature

[@naveennataraj1578]

What about constant voltage drop model?

[@lotfullahandishmand753]

why we cant takein both PN junction for ideal diode Vd=0?

[@shamshadali5332]

Sir diode ki category btaye

[@TipsRacK1]

the forward and reverse bias is the other way around..

[@roshithkuchadi2785]

Sir ideal diode means what....

[@rakeshraj688]

sir at the last moment you say that in case of forward bias (ideal)if resistance is zero then voltage across diode is zero but sir i think.....vol across diode is const it is true or false...

[@samuelsumbo7693]

kudos

[@vipultyagi7220]

great

[@srijanisallyouneed]

By the way... thanks for the video
