Maximum 4A possible, MJ2955 is pnp and has low Beta, 2N3055 is npn and it’s Beta is better, but for 5A you take better darlington TIP120 npn or TIP 125 pnp with Beta abt 1000, for 10A take 2 in parallel with 2 emitter resistors 0R1, bases and collectors each wired together, collectors in, emitters wired out, bases control, poti only 50 mA max current The best solution is the Darlington MJ 11016 ISC with 30A current max and 120V E/C (!) to be found at Reichelt Germany abt € 4.00

Trying to draw 15 amps will destroy the pot. Trying to produce any voltage much less than the supply voltage, at anything approaching 15 amps will destroy the transistor. It's been a long time since I saw someone misuse a transistor/heat sink like this one. For heaven's sake, mount the transistor the way it's intended.

Zafer showed the potentiometer value as 220k. That's much too much - the pot should be less , maybe 10k or 2k. Also the center lead of the pot should be connected to the power transistor's base with a 470 ohm resistor. The tan wire will allow the high current to go through the pot when it is turned to the end, damaging the pot and burning out the base of the transistor. Thanks for the video.

That upside down mounted 2N3055 will not make a good thermal contact with the Heatsink. So there is no way it is going to give you 15AMP.

The total power disipation can be calculated by substracting V input minus V output times the sinking amperes. It is hard to find a power transistor that withstands such parameters.

Przy dużym (około 5A i więcej) prądzie obciążenia, jest niemal pewne, że potencjometr ulegnie zniszczeniu w jednej ze skrajnych pozycji, gdyż przepłynie przez niego zbyt duży prąd bazy tranzystora mocy. Potrzeba użyć potencjometru o mocy 0,5 W lub więcej, albo zastosować układ Darlingtona z pierwszym tranzystorem mniejszej mocy, a tym samym mniejszym prądem bazy.// With a high load current (about 5A and more), it is almost certain that the potentiometer will be destroyed in one of the extreme positions because too much base current of the power transistor will flow through it. It is necessary to use a potentiometer with a power of 0.5 W or more, or use a Darlington circuit with the first transistor of lower power, and therefore lower base current.

You are smart electronics, Mister. But don't show to young enthusiasts which watching you videos this things: it's bad idea to mount elements at radiator using hot glue. And silicon structure of transistor is mounted at thick part of chassis for better cooling so it's impossible to work your regulator with 15A current with transistor mounted "head" to heatsink...

Sir wuld that circuet work for controling alternator voltage regulator? The thing is I like to use plasma ignition😅 on my ignition coil ordinary ceramic 3kw capacitors in series on + coil side and simply ground other side . The effect on my delco 12si alternator is that the cutt in current or some peopel call it starting charge rpm get swaped around . So my alternator is constantly back feading true the dash bulb on normal idel engine speed so I must increase the engine rpm to shut the bulb off at around 3000-4000rpm my alternator charges normali. So any one has idea how I can counter that effect??? I suspect my alternator voltage regulator is also ground voltage controled . So honestly I dono how to fix this problem some peopel sugested resistor/capacitor box some say cloosed loop voltage regulator some phase shifting Im realy confused what to do Im cinde of desperate 😅
