[@sahilkadam1837]

exactly what I was looking for, to teach as well as demonstrate. You earned a new sub sir!

[@TEKNOISTIX]

Thanks 😊

[@debarajnanda7130]

Verynice i make that and working very fine dhanyabad 👍

[@susudarake]

Bhai, aapne AC ko control karne ka banaya hai?

[@rajupatel-js1qd]

thank you so much sirji aap bahot acche se padhate ho.
koi saval baki nahi rah jata. sab javab ek hi video me mil jata hay.

[@sanjaysonihisar6595]

Paaji tussi great ho... Aapne sab achhe se smjhaya

[@JackSparrow-oq6iv]

You put 2 resistors 1Ohm 5W . If the output current is 10A it means that through 1 resistor flows 5A current. P= I*I*R in this case P=5A*5A*1Ohm=25W it means 5 times more power than it can reach ceause it's only 5W. Maximum output current you can withstand with these resistors is 4.5 A.

[@ravirao5798]

If it 4.5 Amps there will be a drop of 4.5 volts...

[@boonedockjourneyman7979]

This guy knows nothing. He copied this from a common exam question without figuring out the answer.
This is a sad statement of the clickbait coming from the Indian EE want-a-be community.

[@muhsen61]

If the transfomer is 30 volt out . This circuit is maximum 2 amps

[@nagarajn4972]

1405. Minutes. 0 is removed. Than the current is 2.5 amp

[@Paul.Smith1980]

This supply will not work the output voltage drop will be significant.Just put multimeter on this supply output.Then aimply attach a twisted pair wire on output without any load attached to wire u will see voltage drop.There is no load yet output voltage will drop.Transistor will conduct uncontrollable just with wire.

[@engahmeds]

when the output current is 10A, each resistor has current of 5A, so the voltage drop on each one ohm resistor is 5V. in this case each resistor should dissipate 25W, while your resistors 5W only !

[@hp2073]

Yeah that's why the only people who compliment are beginners

[@wernerpeter9706]

Your calculation is only correct in the event of a short circuit. With normal use, a few volts should still be available for the connected load, i.e. the voltage drop across the resistors should not be 5 volts.
The weak points are rather the small capacitor after the rectifier and the undersized heat sink. Calculate the power dissipation of the transistors when a small voltage with a lot of amperes is set.

[@hp2073]

@@wernerpeter9706 no difference. Short circuit in a cc supply does not necessarily mean highest current. Power resistors are under rated

[@engahmeds]

@@wernerpeter9706 also in case of full load which is 10A , my calculation is correct

[@wernerpeter9706]

Sorry - that was actually a 1 ohm resistor on the emitter, so in the end I didn't look properly. Yes, you are right, this is a nice heater. 0.1 ohms would be enough to stabilize the load. But then there are still the problems I mentioned.

[@kkvishwanath8278]

...If the voltage is close to zero volts and the current draw is 10 amps, each transistor will have to dissipate 150 Watts...

A pleasure to watch and learn from this video like your last one. You may please ignore my proposal I had stated in your last video comment because the same is very nicely answered here. Thank you once again.

[@TEKNOISTIX]

Thanks
I always try to go step by step in my videos
Firstly i covered the simple fixed power supply
After that in this video i moved to a variable one
And there is one more video in this series in that i have added a volt current display also and also assembled this circuit in a wooden box.

[@dheerajakkr5052]

Bro it would better to give the list materials that you have used in this project in the description. The links provided by you for sourcing the materials is too expensive, that it it will be better for someone to buy a readymade power supply rather than wasting their time and money 😎.

[@vintagerestoration2252]

No need to say your work inspired others. Simple and best explanation that common man can aslo understand. Can pls made a this all 0 to 10 amp and 0 to 30 volts bench adapter for me. What will be the cost I will pay you online.
