Hello,
i have made a variable voltage source but i didnt get the desired output current .
Suggest me to the way to increase current withuout changing the current with circuit.
I have seen so many methods but i dont know how to use it?
i have tried emmiter follower and common emmiter but voltage is changing at the output.
desired output current 200ma.
Thanks,
palak Patel
 

Hello Patel, It would be easy to answer your question in an appropriate way if you could elaborate your circuit and your application requirments.
 
hi palak,
Could you post a circuit of your power supply, its impossible to suggest changes without seeing your circuit.

Hello!

You CANNOT control current and voltage simultaneously.
If you want 200 mA, then you have to adjust the voltage so that you have 200 mA.
If you want to define the voltage, then the current will depend on your load.
