Nice vedeo but you have not describe that why 220 ohm resistance is used in Optocupler , why not 500 hundred, pls tell to student theoretically and calculation. Otherwise vedeo is goo. Pls don't mind. You also miss the starting voltages to ic.
Bhai ohm law use karenge V=IxR, toh 220 ohm ke value ki resister lagegi, agar aap jyada ohms ki used karoge to LED glow nahi karegi aur photo transistor on nahi hoga... LED Glow karne ke liye low voltage chahiye rehti hai...
Sir video bahut acha hai, Mare 2 question hai Sir mare pas ek dth ki power supply hai 1) sir ji tl431 ki 1pin ref. 2nd pin gnd input aur 3rd pin gnd out aur gnd(ground) optocoupler Ko Mil Jata Hai Lakin tl431 ki reference pin per voltage divider Banakar 2.5 V Diye Jaate Hain Aur ye + voltage hain, pr ishi ref. Pin pr ek capestor laga h (35v, 47uf) is capestor ka "-" Pin ref. Ke "+" Voltage pr laga hain , Aur ishi capestor ka "+" Pin tl431 ke ground output pr kaga hain, asha ku? 2nd) Mere wali Supply main optocoupler ki 3 number pin direct 300 volt ground se Judi hai aur 4 number pin switching ic main ja rahi hai Pr aap wali Supply main 3 aur 4 number pin dono he ic se judi hain asha ku? Please reply 🙏 Thank you
crystal clear explain sir u r realy very good teacher sir thanks sir
Thank u so much
Very good video sir ji. Sir aapake Jaise UA-cam par bahut kam video dhekhane ko milte hai.
Thanks u so much
Sir aap bhut aacha samjhate ho...
Great knowledgeable video, Thanks 👍
So nice of you
Bahut achhe tarika hai aapka samjhane ka sir Ji
Bhai sahab aap nai bohot achcha samjaya thanks Bhai sahab str Power supply bhe samjhana
I will next video
Osm great🎉🎉
Ossam sir ji
नॉलेज बहुत फायदेमंद है
Video Time 14:12 par kaise plus banega.... Explain sir
Super video
Wahh sir ji ❤
Very good sir ji
👍🙏

Sr 260diod garam hone ka kya Karan hai pls batay 100mfd.open.karne per garam nahi hota hai
Sir filter capacitor 400 plus voltage ka lagathehai lekin kitne MFD ka hona chaiye
Sir agr koi diode shot ho jaye our same na miley to kon sa laga saktey है.
Sir video bahut acha hai,
Mare 2 question hai
Sir mare pas ek dth ki power supply hai
1)
sir ji tl431 ki 1pin ref. 2nd pin gnd input aur 3rd pin gnd out aur gnd(ground) optocoupler Ko Mil Jata Hai
Lakin tl431 ki reference pin per voltage divider Banakar 2.5 V Diye Jaate Hain

Aur ishi capestor ka "+" Pin tl431 ke ground output pr kaga hain, asha ku?
2nd)
Mere wali Supply main optocoupler ki 3 number pin direct 300 volt ground se Judi hai aur 4 number pin switching ic main ja rahi hai
Pr aap wali Supply main 3 aur 4 number pin dono he ic se judi hain asha ku?
Please reply 🙏
Thank you
केपेसिटर विक होगा तो कया रीजन होगा ? वो तो बताओ। धन्यवाद।ज्यातर आ,,पुट पावर अन स्टेबल रहता उसका भी रीजन बताए सर।
sir je inverter ac pcb cummnucation circuit diagram bana k sumjay kindly
Yes I will
Sir ek ic itna sara voltage keise bonata hai
IC voltage nhi bnati ic voltage jo emplyfire and switching karati hai
