Say i have a 3V and .01mA input is it possible to increase the current to almost 200mA???If it is possible what kind of circuit i must use???pls.. help me...

The simple way is to get a higher voltage battery. But you might fry your circuit.

Yes, but that's a lot of current gain. You're talking about a gain of 20,000 in current. You'll need a multistage amplifier which will be kind of complicated. If you want the output to follow the input as it varies exactly, you'll need to use some feedback. At that kind of gain, stability will definitely be a problem. Good luck. There's no simple answer you'll get from here.

Decrease the resistance of your circuit to 1/20,000th

Yes.
For that we have to use a transtior of current amplification factor of 2lakhs. If it is possible then that is also possible.
Current amplification factor is the ratio of input current to output current.

Your question does not make sense. A circuit that uses only 0.01 mA, would be destroyed if you tried to put 200 mA into it.

You need more voltage or less resistance at your input.
