Mr G K Grawal if you have a single wire line coming to a room without neutral..and you want to connect it to device without neutral direct to earth...is it possible ?? And what are the consequences of you complete the circuit through the earth of the ground in the room ?
Many have asked this. Electrical drg are made in many ways. I myself made electrical panel drg running into many many 1000 pages. But I do not have any drg now with me. Then how to explain? All drgs are property of some company and can not be used by me in any way. Can you tell, exactly what type of drg, like small circuit diagram, or one panel, or SLD of system, you are talking about.
Sir, answer to this question in the last of the video should be "AC with very very less frequency" according to me. Thank you sir for this very interesting & knowledge-full video.😀😁😂😃😄😅😆
Sir in your 22 no point . It looks relative type problem or seeing things in smaller and big spectrum . Wave in smaller spectrum is dc but in bigger and actual spectrum is ac ..M.zakir
Gopal ji, maine padha tha ki DC transmission to long distance efficient nahin hai, HVDC ke dwara hai par core DC pe kya yah theory laagu hoti hai? agar hoti hai to kyuon?
HVDC hi DC transmission hota hai. HVDC kaa matlab hai, high voltage DC transmission. High voltage esliye add kiya kiyoki, power transmission high voltage mey hi hota hai, HVAC or HVDC Yeh aapney kaha padha ki DC transmission long distance mey efficient nahi hota hai ?
Before writing like this, you should check paper written by electrical industrial experts, or atleast check wikipedia. Otherwise you will get wrong knowledge. Just search, DC transmission wikipedia.
Sir I have one doubt, current will folws in closed circuit then electrons from the transmission lines flow to distribution line then after load drawn the current but my question is where does the generated electrons are going it must be return back to the generator through neutral wire ryt Sir then only it becomes closed circuit ???
G K Agrawal sir amp transformor ki coil ki turns aur wire size mai nirbhar hota hai kya ? amp ko unlimited bana nai sakte kya ? Sir ghar mai 220 volt ataa hai ye transformor kitna amp kaa hota hai ? limited hota hai ya unlimited hota hai ?
AC has skin effect in transmission. This causes magnetisation and demagnetisation of the conductor which leads to hysteresis. Due to hysteresis loss and instability problem arises. I hope I cleared your doubt.....
sahi bataya hai dc transmission is ecnomical for long distance because in ac transmission due to very high voltage cost of towers and losses will more and ac is ecnomical for short distance
Sir , if a system supplied a dc voltage for battery charging. Then which load is required to measure the electricity consumption. Is it AC load or DC load ? Need ur guidelines. Regards
गुरुजी जब किसी कंडक्टर को हम 230 वोल्ट के सॉकेट में डालते है तो शॉट हो जाता है ।। किन्तु प्राइमरी coil के दोनों end को 230 सॉकेट में डालने पे शॉट सर्किट काहे नही होता ???? सिंपल भाषा मे बताने की कृपा करें
किसी तार का resistance बहुत कम होता है तो करंट ज्यादा बहने से short हो जाता है लेकिन ट्रांसफार्मर की प्राइमरी में इंडक्टेंस होता है जिसकी वजह से current कम बहती है और शार्ट नहीं होता

Sir in 7th point total peak is not 25 V simple airthmetic sum is not used for addition. for this phasor sum is used like this peak value = √20^2+5^2 =√425=20.6 V
25 volt peak told by me is correct. Your calculation is for 2 vectors with 90 degree phase angle difference. That is not the case here. You must watch my video on 4 study tips for science study.
@G K Agrawal सर एक ट्रान्सफरमर 12 volt 15 amp का हे ईश ट्रान्सफरमर से 12 volt 30 amp load का equipment चलेगा ? अगर करेन्ट fix नहि हाेता हे ताे चलना पडेगा अगर current fix हाेता हे ताे नहि चलेगा 30 amp तक का ट्रान्सफरमर जरुरत पडेगा मतलब घरमे अाने वाला 220 volt का ट्रान्सफरमर कितने amp का हाेता हे लिमिटेट हाेता हे या अनलिमिटेट हाेता हे ?

Very exclusive information. Point number 22 is 1st time in the world. It change our understanding of the AC and DC.
This is called real knowledge
Excellent . You are special GURU.
Awesome awesome awesome, Sir, Kayi chij clear ho gyi Sir, Thanks a lot Sir.
mainey 375 videos banaye hai.
Your way of teaching is really good mr.aggrawal.
Excellent video on AC and DC difference
Which is most important difference between AC and DC, explained in this video is as per you,?
AC Transmission vs HVDC Transmission.
Just saw a video of khan sir he told ac could be transmitted to long distance but dc could be transmitted to short distance. This is conflicting

Sir 22 me time ko bhut jyda fast forward KR de to AC h. 1 year ki jghe 1sec. KR de to AC h ......... Sir very different & good question .
This unique question is asked to make mind think in many direction, while analyzing AC and DC system. This is the way, experts think.
Comments welcome

Dear Sir why we use fuse in positive & Negative in D C Circuit
Fuse is used in AC circuit also.
Sir I have one doubt, current will folws in closed circuit then electrons from the transmission lines flow to distribution line then after load drawn the current but my question is where does the generated electrons are going it must be return back to the generator through neutral wire ryt Sir then only it becomes closed circuit ???
Watch my video on 3 phase supply concept.
Great work
So so so nice explanations sir
Sir point 22 is also like we think that earth is flat because of narrow vision but in actual and larger spectrum it is oval / or round type.
And I hope, nobody in the whole world might have not told this, atleast I did not see.
Thanks sir . Your lectures are helping us in clearing concepts.
nice
Thanks sir for giving us an expensive lesson
Plz make a video on Electrical drawing oR MEP work...
Great sir

Current unlimited nahi hota hai.

Jo hota hai wo dikhta nahi ,aur jo dikhta hai wo hota nahi...life b aisi hi hai sir ji ,juz like expanded sine wave .

Please explain stability problem in AC transmission
AC has skin effect in transmission. This causes magnetisation and demagnetisation of the conductor which leads to hysteresis. Due to hysteresis loss and instability problem arises. I hope I cleared your doubt.....

Watch my video on 3 phase power supply , and also phase line voltage difference.
Sir which is more dangerous Is it ac current or dc current at same voltage? If already video is there pls share the link...I ll be thankful.
Watch this video again full 2 times with concentration.
🙏🙏🙏🙏🙏🙏
sir AC is good in transmitting long distances not dc
I have worked in HVDC design department for 12 years, still you do not want to learn from me, then it is your choice.
sahi bataya hai dc transmission is ecnomical for long distance because in ac transmission due to very high voltage cost of towers and losses will more and ac is ecnomical for short distance

Sir AC KO DC, & DC KO AC me convert karne ke process ko kya bola jata hai? I think eliminate or rectification?
AC ->DC is performed by Rectifiers
DC->AC is done by Inverters
