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,

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.
