Computer SMPS par bhi ek video sir.
Jaldi hi computer SMPS bhi karenge 👍
सर वैसे तो आप बहुत ही अच्छा समझाते हैं लेकिन एक संदेह भी हैं जब आप्टोकप्लर की एल इ डी 20 मीली एंपीयर का पावर उपयोग करेगी और उसके समानांतर में लगा रजिस्टेंस जो कि 60ओम्स का हैं तो वह भी 20 मीली एंपीयर का उपयोग करेगा परिणाम स्वरूप जेनर डायोड पर 40 मीली एंपीयर का भार होगा।
जबकि होना यह चाहिए कि आप्टोकप्लर की एल इ डी के सीरीज में यह रजिस्टेंस लगनी चाहिए जो कि एक एल इ डी के लिए आवश्यक भी है।
Solar ka Upar Kuchh video banaaiye mppt Technology controller 40 volt solar Se Kaise 12 volt battery charge kar sakta hai usko Upar Kuchh video banaaiye please aapko video mere ko bahut Achcha lagta hai main Bahrain baith kar dekhta hai theek hai ji bahut Achcha Achcha video aap Banai ja raha hai daily daily Meherbani
Shukran akhi ❤️👍
Video kafi knowledgeable hai, thanks,ek nivedan hai sir jaise aapne 60 ohms ki resistance to calculate kar li aur bata diya , lekin sir 60 ohms ki resistor market me easily available nahi hai to uski jagah 120 ohms ki do resistance parallel me laga kar 60 ohms ki resistance ban jati hai, theek usi tarah se 10.8 volt ka zener easily available nahi hai to uski jagah kya laga sakte hain,sir inko kaise calculate karna hai ye bhi bataye, meherbani hogi
Shukriya Dost ❤️👍
Ye video kewal calculation kaise karni hai, wo samjhane ke liye tha. Aage aane wale videos me hum actual values par bhi baat karenge...👍
Pl explain inverter welding machine
After SMPS tutorials...
Zener diode ka current 40 Milli ampere hona chahiye
🙏 sir what am I asking is right or wrong? We are connecting led and resistor in parallel so current of it will be sum of both. So current is going through Zener diode will not be 40mA? Is this right or wrong. I m mechanical engineering person but want to learn electronics from such a confident person like you. 🙏🙏🙏
You are right brother but as per the datasheet, the optocoupler's LED's maximum permissible current is 20ma. We still kept zener current as 20ma because we want LED to be safe. When LED and the resistance will share that 20ma togather, the LED's current will never exceed 20ma and this will keep it within safe working range. Hope it is clear now. 🙏
Agar yaha optocoupler ki parallel mei resistor nehi use kiya to kiya hoga?zener diod to already voltage ko drop kardegi.or acchase samjaiye plz or satme yebi bataiye resistor valu jada honese kiya hoga or kam honese kiya hoga
Resistor nahi lagane par extra voltage ko drop hone ke liye koi jagah nahi hogi aur poora load zener par padega aur wo kharab ho sakta hai dost...
Thank u so much reply karneke liye,apki video dekke mene bohot kuch sikha lekin resistor ki puri working muje samajme nehi ati,resistor kabi series me or kabi parallel me use hotihe kabi voltage drop karneke liye kabi currentko limit karneke liye.muje lagtahe serf resistor ki barome abi bohot kuch jana joruri he mereliye
Sir jo China ke charger hote he local
jisme zener diode or Tl431 or optocoupler nahi hote he
sir jisme resistor hote feedback ke liye 12 volt me kar dijiye
par sir ek request he graund ka resistor kon sa hota he samjha dena kaafi time ho gya wait karte
OK brother ❤️👍
Sir ji Hair washing machine ke timer circuit kaise kaam karta hai
Ye baad me discuss karenge dost..
Sir current to optocoupler ki led sa ho ka bhi ground ho sakta tha par es ka saath parallel ma resistor kyun lgai jaati hai
Voltage drop karwane ke liye dost ❤️👍
share the method of voltage calculation
Which voltage you are taking about brother ?
Excellent Sir.es diagram 10.2 volt ka zener revers bais laga ha 10.2 volt drop hovai 1.2 led per pohoncha agar zener forward bais lagaya jaye to kia situation hogi?
Thank you sir.
Agar zener forward bias me lagaya to zener par sirf 0.7v hi drop honge aur 11.3v series resistor par aa jayenge...Jo ki LED ko kharab kar denge ..
@@vccground-hindi thank you sir
Sir current parallel me distribute hoti hai ... Toh. Kya led section me current... Alag hugo
Aapka sawaal samjh nahi aaya dost 🤔
Sir, if I don't have 10.8v zener & I have 9v zener then can I calculate with same manner maintaining 12v output?
No Sir, Zener voltage should be correct.
Bhai saheb mobile charger me optocupler nahi lgaya gaya hai to feadebacke kaise Jane ki kaun si resistance di gayi hai
Bina optocoupler Wale mobile charger ki video bhi aage aane wali Hain. Usme samjha denge 👍
sir mai 12 ya 25 volt ki supply h direct tl 431 me + n _ lagau aur tl 431 1pin pr 10k ka pot lagau jisse volt variable hoga to smps ki + ke sath sersir resister kon se value ki lagegi take tl431 kharab na ho plz rply
10k ki resistance laga do ❤️👍
Sir I think current flow in zener is 20+20=40mA . Are you agree?
Yes brother
To sir kya optocoupler ki led sa nahi voltage drop honga
LED par lagbhag 1v hi drop hota hai...
कृपया inductor के बारे मे पुरी जानकारी दें। किसी भी coil की value कैसे देखें । अगर ये खराब हो जाए तो उसकी जगह कोई भी क्वाइल लगा सकते है कि नहीं? रेजिस्टर टाइप क्वाइल की रीडिगं,उसकी वाटेज आदि सारी जानकारी विस्तार से बताने का कष्ट करें। धन्यवाद
ज़रूर दोस्त 👍
Sir output Capacitor kharab honepar output voltage lode connect karnepar kyu down hota hai
Kyuki capacitor kharab hone par wo poore voltage level ko hold nahi kar pata hai, iss liye load lagane par voltage down ho jata hai...
Zener diode 10.8v block karke 1.2v pass karta hai, ussi 1.2v l.e.d ko on karte hai. L.e.d k 2nd leg ground hai. Question hai ki yeh jo 60ohm ki resistor lagaya jata hai, yeh kis liye? Same question, Voltage divider me jo nichewala resistor hota hai, jiske across tl431 ko on kiya jata hai oske liye v hai. Help me dost.
Sir ji ager out volt 24v hai tab r ki value kaya hogi
R ki value to wahi rahegi, zener diode ki voltage aur wattage badal jayegi dost ❤️👍
sir zener diode 10.8v ka nahi ata he fir konsi value ka zener lagana chahiye please reply
11V ka laga do, optocoupler LED 0.8v tak bhi kaam karti hai .. 👍
sir, ek doubt hai.. agar hum 10.8 v ka zener lagayen toh resistor lagane ki jarurat kyun hai..?
Extra current ko drop karne ke liye. Nahi to LED kharab ho jayegi...
@@vccground-hindi sir hamko toh sirk 1.2 v hi chahia.... toh ye resistor zener k protection k lia hai..
The current through the Zener diode should be 40 mA otherwise the KCL at the node connecting the three elements will not be satisfied.
As per KCL, You are absolutely correct brother. But here we are calculating for absolute maximum values. 20ma is the maximum current value to be passed through the LED but under ideal condition this would be lower than that. If in any circumstances, the resistance opens or the LED gets faulty, the remaining branch should be able to handle at least 20ma of current flow through it. So 20ma would be the maximum current passing through the diode. That's why, in practical feedback circuits, you will always find a half watt zener installed.
I strongly believe that current through zener must be 40 mA due to loading effect,if zener current as per your explanation is 20 mA then current through opto led and 60 ohm resistor would be 10 mA each. please correct me if I am wrong.
@@manhardanmahedu3765 Theoretically you are absolutely correct brother. But here we are calculating for absolute maximum values. 20ma is the maximum current value to be passed through the LED but under ideal condition this would be lower than that. If in any circumstances, the resistance opens or the LED gets faulty, the remaining branch should be able to handle at least 20ma of current flow through it. So practically, 20ma would be the maximum current passing through the diode.
But value of current in ziner diode and octocupler led and resistance is not same 20 mA
