    Application of 7805

    Hello Kris sir, I would like to tell you the purpose of this circuit. I want to build voltage source of 5V capable enough to supply more than rated current of 7805 ic. I searched a lot and then found the circuit that I have posted. Now to make use of this large current I used it to trigger...

    Application of 7805

    Hi to all, I was working on the attached circuit. My aim is to make sure that transistor Q2's base terminal gets about 1A current. If anyone can please let me know whether this will happen in the attached circuit then it will be highly appreciated.

    Application of 7805

    Hello, @CDRIVE Can I connect base resistance and 2N3055 in place of the load? As I have shown in the figure.

    Application of 7805

    Hi steve, The problem is that maximum base emitter voltage of 2N3055 is 7V. So I tried to remain in this limit by using 7805 ic.

    Application of 7805

    Hello sir, I apologize, in place of 2N2222 there is 2N3055 power transistor. From this circuit I want to drive the transistor to high current. All I am trying is to make sure that base of transistor receives current of about 1A.

    Application of 7805

    Hi, I have attached the circuit. In this I was trying to get high current across resistance R2. But as soon as the circuit is connected the voltage dips to 0.8 volt (across R2 and base-emitter junction). But if I remove the transistor and then ground the other terminal of R2. Then a large...
