Sir aapne repeated questions bhi har baar explain Kiya.....agar koi chapter nai bhi padha hoga yaa thoda padha hoga usko pura chapter revise ho jayega ....hats off to you sir ..❤
Self notes Semiconductors important questions 1) 34:46 ( see 2 cases of conductor band )........2) 56:09( must see 2nd part )...........3) 1:10:03 ( rem. Circuit diagram ).........4) 1:20:30 (Sb - Antimony (mistake )
@@himalaychaudhary2846 bro 25 students ko sahi lga h tumhe hi glt lga hai. , tumhi jaake ek baar khud hi pdh lo.....or kbhi reply krna to pdh ke hi krna ...👍
REQUEST🙏👇👇:- Sir...your one shot + pyq series really help me a lot in my hair yearly as well PT:4...sir...but it's my one request as well as suggestions that:- please start an another series in which you solve some sample paper...with timing... Because by the help of this series...we practice according to CBSE exam...
49:35 sir this question was about the difference between intrinsic and extrinsic and you gave the difference between p and n type which are types of extrinsic semiconductors!!
18:25 sir forward ka diagram mein mistake h 46:56 group 13 in p type , group 15 in n type 1:03:35 (a) the resistance of a PN junction is low in forward bias because the majority carriers are attracted towards the junction, making it easier for current to flow. In reverse bias, the majority carriers are pushed away, creating a wider depletion region and higher resistance.😊🔌 (b)the reason we need to dope intrinsic semiconductors is to introduce impurities that can alter their electrical properties. By adding impurities, we can create either p-type or n-type semiconductors, which are essential for building electronic devices like transistors. Doping allows us to control the conductivity and make the semiconductor more suitable for specific applications. It's like giving the semiconductor a little boost to do its job better! ⚡️ Hope it helps
You are a brilliant teacher.... absolutely brilliant....in such a short time you have taught such imp concepts interestingly...no one can beat your teaching🔥🔥🔥
Thank you sir ❤ literally this video helped me a lot I was worried about this chapter which type of questions will they make it from this chapter but this video helped me a lot thank you once again sir ❤
Sir these series is one of the best for revision...... Thank u for this one..... With your such a beautiful smile the toughest concept of physics also seems very easy
Sirjiii apki explanation and way of speaking outrageous hai merko toh exhausted ho jaata hu padh ke phir bhi aapki aawaj me alag hi positive vibe aati hai didi jab 12th me thi toh aapke videos se padha karti thi tabse aapke baare me jaanta huu aur ab khud ke boards ke liye aapse padhne ka saubhagya mila hai! 🥳 Aashirvaad dijiye Gurujii jeewan me ek safal insaan ban sakuu 🙏🙏🙏
Sir ur videos are good but i want to suggest take another page instead of doing it on same or u can decrease the size of slide while we are writing or taking ss bcz it wil be more convenient for us
Sir , I am from assam board , Hamara yaha v syllabus lag vag same hai as cbse But mujhe lagta hai isbar thora sa tough aane wala hai otherwise bohot sare options hai To kya sir ye questions me dex sakta hu , kya isme SARE TOPICS AND TYPES COVERED HAI IN THE WHOLE PLAYLIST
sir 29:30 yha question me aapne equal holes or eqal electron kyu liye h equal honke to nuetral bna lenge fir move kyu krenge p me holes jyada honge or n type me electron jyada honge na sir
Thank you so much sir 🙏🙏🙏🙏🙏🙏🙏🙏 your explanation is so nice 🎉🎉🎉 sir ek question hai one short or pyq se or MCQ series se ho jayga complete jisse hum 90+ achieve ke ske ?🎉🎉.
