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।

@prasadkarlekar7856 8 месяцев назад

🙏 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. 🙏🙏🙏

@vccground-hindi 8 месяцев назад

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. 🙏

But value of current in ziner diode and octocupler led and resistance is not same 20 mA

@raviparkashsharma3271 8 месяцев назад

The current through the Zener diode should be 40 mA otherwise the KCL at the node connecting the three elements will not be satisfied.

@vccground-hindi 8 месяцев назад

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.

@manhardanmahedu3765 7 месяцев назад

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.
