Kaise hain sar tiktok hai aap sar mujhe ek baat bataen ki yah KVR aur kilowatt yah generator ke andar agar KVR ho to uska kya matlab hai agar kilo wat ho to uska kya matlab hai
Sir inverter का current attractive in nature hota h ya phr a. C or aise hota kyu hai ki. Ek current body ko fek deta h durr or ek current body ko chipka k rkhta h device se
Sir voltage and current kitni baar pdhlo shi se smjh ni aata.. Jaise transmission lines me agr ac flow hoti h toh current flow me resistance jyada hota h agr ushi ki voltage high kr de toh heat loss negligible hota hai... Toh ishka kya mtlb ki voltage jyada hone se current flow hi nhi krega.. Sirf voltage flow kregi... Or phr voltage flow, current hi toh hota h na agr dekha jaye toh.. Potential difference = voltage, voltage flow hone se current km kaise flow hoga sir practically
P=VxI, power fix hai tho voltage jyada hone per current less hogi. Mera vidio voltage badhne per current less hogi yaa badhegi देखो. Aapko pahle dekhna hai ki resistance fix hai yaa power fix hai.
भाई साहब मैं आपसे यह पूछना चाह रहा था कि यदि फंक्शन जेनरेटर को हम ऑफ करके on कर देते हैं तो वह फिर से अपनी पहले वाली फ्रीक्वेंसी दिखाने लगता है क्या ऐसा नहीं हो सकता कि वह जिस फ्रीक्वेंसी पर सेट करें उसी पर सेट बना रहे.
All 4 answers are correct, good. However, if we apply 3 phase power, then resistance between 2 point , in last 2 answer, is of little use, As current will not flow in line wire using 60 or 20 ohms.
If I use an auto-transformer as an audio output to increase the output voltage on the amplifier, for example 40v input and 100v output, is it relevant? please give feedback 🙏 thank you
Theoritically ok, you can try, but there may be 2 problems 1 - Your amp output should be able to drive auto transformer. 2 - Normal auto transformer core may have high loss at high frequencies. In olden days, a small 1 inch by 1 inch size transformer were used in audio amp circuit.
@@GKAgrawal2 I have tried it, increasing the output of the OCL amplifier using a 37-0-37 transformer, it turns out it works well, the audio frequency can be said to be safe, without defects. After this I want to wind the 0-40v-70v-100v automatic transformer myself. with 500va power at 0-100v. Thank you for the explanation, sir.
