Good sir

Sir, i am new watching your youtube channel.

Nice project sir. Can you plssss put english subtitle? Thank you.

Nice video sir, can I use 6-0-6 v 1A transformer?

If we have to charge a lead acid battery, the charging current must be one tenth of AH. If AH is ,say , 5, the charging current is 0.5 Amp. So, the capacitor must be able to supply that current. Now, how to decide capacitance ? Kindly explain.

Your video is very good but for new person it is difficult to know the wattage of resistance kindly provide resistance wattage

I like this important video. Thank you.

Dada, iss charger mein autocut nehi hai toh battery overcharge hoke damage ho sakta hai. Aur aap ne nehi bataya ki kitna ampere ka battery charge ho sakta hai ?

470k resistor 1/2watt or 1 watt? Pl.confirm.

Sir is circuit ka preset ko kaise calibration kare usko video mein nahi dikhaya gaya, plss usko clearly batayein, wo bilkul bhi nhi smjh aya, full chrge bttry connect krke calibration kaise karein? Aur bttry full charge hain ke nahi wo kaise check karein?

இந்த 4 volt பேட்டரி charging செய்யும் method constant voltage charging method. இந்த constant volt charging யில் தொடக்கத்தில் full current flow ஆகும். பிறகு சிறிது சிறிதாக குறையும். இப்படி குறைவது 0.1* initial current என்ற அளவை அடையும் போது பேட்டாி full charge ஆகிவிட்டது என்பதே அடிப்படை.மற்றபடி பேட்டாி volt தொடக்கதிலிருந்து முடிவு வரை 4.7 என்ற threshold volt யிலேயே தான் இருக்க வேண்டும்.

Please मुझे यह बताएं कि बिना बैटरी के कौन सी led glow होगी। में इस सर्किट को 9 volt DC सप्लाई दी है परंतु जब green led glow करती तो red led बंद हो जाती है और जब red led glow करती है तो ग्रीन led बंद हो जाती है और output voltage भी 4.30 पर भी set नही हो रहा। प्लीज help
