    Is it possible to increase 0.5 amps to 3.5 amps using aimple amplifying circuit.

    Short answer. No. If you can tell us what you're trying to do can can give you a better, longer answer.

    simple amplification

    ok is it possible to double volts and amps at the same time, etc 10v to 20v and 1amp to 2amps, (10v 1 amp to 20v 2 amps) using a simple circuit.

    No. The energy available will always be the same. You can transform it, but not create it.

    in fact the opposite, if you double the voltage , you are going to halve the current available

    as LTX71CM the energy (Power) available doesnt change

    that is if you have a power supply capable of supplying 100Watts. that can be 20V @ 5 amps or 5V @ 20 amps or any variation there of. Whatever you Volts and Amps they have to equal 100W max when multiplied together.

    Yes, this is quite simple. BUT the circuit will require it's own power supply capable of providing the full output voltage and current you require.
