1. If I have a fixed (non-adjustable) regulated signal 1V at 10A DC (just for example), will I be able to control the current (for example vary from 9-10A DC) without making signal become "unregulated" DC signal?

2. If I have an adjustable regulated signal (1-5V) at 2A, will I be able to amplifier the current to 10A without making signal become "unregulated" DC signal and the voltage still adjustable from 1-5V?

1. If you add .011 ohms in series with load of 1 ohm current will drop to 9 A from 10 A.
2. Use an OP amp with a high current darlington transistor within feedback loop to lower output impedance. Additional power supplies will be needed.

1. Should it be in parallel because parallel shares the current?


1.2. Will they guarantee that the signal is still regulated?
