XII_97.Semiconductor-Rectifier

[@xmj1279]

Those students are so lucky... Sir you are a legend. Thank you so much. Physics is like so easy because of you sir. I wish i had watched your videos earlier. I knew your channel and the way you teach but i was always procastinating. And now i have finals like after 10 days or so. You're a boon to that particular college where you teach also the students arr like really lucky. PS. Those students dont even make noise during class hours. Like teacher like students i guess. Disciplined 😊

Sir you're a legend, a saviour for a person like me who needs to clear out some topics.Thank Youu.

[@tanaykhanna]

you are very simplified in teaching...great...amazing

[@shivensmom9850]

sir...Happy Diwali 2 u n ur family.....may this diwali fill ur life with happiness n brightness.....

[@AbhishekKumar-pq4hk]

potential will also drop from diode. In H W R only one diode is used and in F W R two diode is used so more potential will drop in F W R ,so less energy

[@monuparashar2600]

M apki video lecture dekhta hun or jo bhi dought hota h vo sb clear ho jata h

[@jitendralad6549]

Jordarr..very helpful video...understood very clearly

[@shubhamsinghrajput7876]

thanxx sir thanxx a alot ,,,, i would hav never been possible to complete semi conductor in one day.. i'm ur fan...

[@AkashBV]

The way of explanation is too good.

[@sheetalmishra2063]

Never studied this chapter in my whole 12th! Just watched these videos and now i know almost everything! Amazing!! ;) Thank you loads ,Sir! :D

[@supriyoduttario8030]

Me too... :)

[@learnearngrowandglow5448]

मेरा भी कुछ याही हाल है

[@ashutoshpurohit8603]

I mean, can we use regulated DC power source to primary winding of transformer? Will it work? If no, then why? Please guide.

[@amangupta9345]

Thank you sir. Sir plz send them as soon as possible .

[@sapthamisatish5865]

sir int his video you told that the 2 output terminals are short circuited using capacitor. but doesn't short circuit allow high current to flow through the circuit and thus spoiling the circuit...........plz reply sir.........

[@arainbros1471]

sir how did you calculate that the voltage drop from 100 to 90 acquires 0.01 secs?

[@ujjwalkapil1]

sir, can you please explain what is meant by voltage drop across a resistor?

[@juhirao4075]

I am very thanxfull sir ....ur teaching method is good ...

[@mainaksanyal9515]

sir kyi books mee filter me inductor bhi series mee place kya hota hai uska kya role hai sir?

[@kritikishor9914]

sir. how charging and discharging in filter is done? in what sense we say short circuit for current in filter?

[@arishtbaid]

i salute you sir for doing such labour for us

[@nehafarooq9025]

Sir what will be the output wave form if the input AC signal is applied in cosine wave form? Abhi ap ny sine wave di hai input mai. Plz cose wave ka btain.

[@archnashukla9815]

sir output wave ka amplitude kam nai hoga than the input one ?? current divide hokar diode tak toh jaye ga....

[@manavbhalla8241]

thank you very much sir. this chapter seems to be tough but when you explained it the concepts got embedded in my mind and I am now it's master

[@supriyoduttario8030]

Sir, is current really dependent on voltage? does voltage works like resistance somehow? what does potential difference really means?

[@shitalkashte1640]

thanx a lot for this video sir.its really very good.

[@akshaykamath7719]

sir ,in full wave the work done on mobile is less no?becos if supose A has a potential of around 10 and c has 5 ,so when the charge carriers reaching c frm A shld hav spent only 5 joules .similarly when charge carriers are moving frm B to C they spend 5 joules,therefore total 10 joules of work is done on mobile.bt in the case of half wave rectifier the charge carriers move frm A to B spending 10 joules of energy as potential of B is 0.hence in bth rectifier the work done is same.plz xplain why?

[@patelmounika8345]

why can't we directly use capacitor(filter) to get dc current?

[@ashutoshpurohit8603]

Sir, in regulated DC power supply, there will there be a changing magnetic flux? So, will emf be induced in another coil in neighbour? If no, then why? Pleae guide.

[@turpatisanyasirao2829]

Pradeep Kshetrapal sir did output current has both ac &idc for load

[@gautammishra1998]

Sir, Will the drop of voltage be exactly 10V(i.e. from 100V to 90V) in 0.01s as the relation between time and charge discharged (of a capacitor and a resistor) is exponential and not linear?

[@gautammishra1998]

+Pradeep Kshetrapal thanks a lot sir.

[@juhirao4075]

Thanx sir ...for explain seprately any students doubt ....u are great sir .....only seeing online vedio and using google i have completed my whole 11th and 12th physics syllabus.....when i am totaly frurste. Then one idea come in my mind see vedio using utube ....

[@bimalmandal6475]

why no current trough reverse bias

[@Vladimirmakarov108]

sir can we use very high resistance in place of transformar

[@revthiii_raj]

Thnku sir for this wonderful class

[@manoranjanmishra7736]

Sir, what will happen if we will not use capacitor in ceiling fan? i think it will not rotate with constant speed. Is it? sir ...plz ....reply and guide me.

[@rohanbhandari7796]

sir is the capacitor not getting charged in the process when voltage again rises from zero?

[@swapnilsonsurkar2136]

sir the way of explanation is so o good

[@sittuc2]

Sir if we Increase the resistance in filter.. soo cant we get much smoother DC..?? because u said resistance will slow up the time of discharging of capacitor soo if high resistance connected then it will take more time.. and as time slows up it will again come to 100 and fill ups the charge in capacitor..??

[@apurva_z13]

sir the diagram of full wave rectifier is different in maharashtra boards textbook and it is bit confusing too,,, so which one would u suggest to draw in boards exam?? yours or state boards textbook one??? please do reply...

[@akshaykamath7719]

sir !apne full wave rectifier ke graph me current ko voltage manliya hey i;e 100,lekin 100 darasal me voltage hey na?

[@nehababra7978]

sir why the short circuit happen when ac pass through capacitor?

[@imranrmd1552]

ripple factor? efficiency?

[@quantlfc]

why is c at lower potential????

[@amantak4001]

sir.. in this is DC current keeps on changing its magnitude with time according to graph?but this is actually AC with no changing direction... so confusing

[@chandrasekharanneelakantan2611]

sir, I have a doubt. u mentioned a term called short circuit. can u explain briefly wat is all abt it...??

[@soundarya8004]

thank you sir. you made physics fun. 😃

[@nagavardhan9018]

But sir why only capacitor allowing only ac to pass through it and where does this ac come from we had already rectified this currents using diodes ?? This is bit confusing me ...sir please make me clear

[@shivaprakashgmath612]

It helped me a lot, thank u sir

[@tanmaysahoo7416]

You are a great teacher sir

[@surbhichauhan37]

Sir can u please upload numericals solutions also of ncert

[@mohammedisrahar6597]

thanks sir this even help for B tech student also

[@jk0340]

Thank you sir! You're great! Sir can I get the notes of this chapter, as requested by other students? East or west Pradeep sir is the best!

[@yogeeshshahapurkar6204]

nice explanation sir..!

[@ashishranjan4864]

thanku vry mch sir m very grateful to u

[@kasukasupmna]

sir why is it said that rms voltage becomes half the actual voltage after passing thru half wave rectifier?

[@thilagaloki9554]

T

[@onkargaikwad8542]

Thank you very much sir.

[@chandrasekharanneelakantan2611]

got it sir, thank u

[@ashishranjan4864]

i want to take ur videos lecture so sir how is it possible for me plz reply me sir

[@digvijaysinghkoranga9522]

can anyone explain me how during positive half cycle of ac one terminal is positive while other is negative..? plz reply fast exams are closer..............

[@chemysteryfun7425]

Digvijay koranga due to the primary part of transformer

[@RAHULSHARMA-qn5bn]

very helpful video Sir

[@monuparashar2600]

Bahut achhe sir

[@sunitakumari-ni5wo]

Sir I want to purchase all 11 and 12, class lecture videos. So is it possible

[@ritikwasekar1947]

sir thank you for this video

[@daaniyaalhariss4212]

why voltage changes from 100 to 90 only
