Supposed you have a certain voltage and resistor values.. for example.. 110 volts and 55 ohms. The current would then be 2 Ampere. Is there a way to boost the amperage value to say 5 ampere without changing the voltage nor the resistance but by doing something to the source??
qude
Accelerate the setup to relativistic speed, then the well known resistance dilatation gets into effect and allows more current to flow :-)

Yes.
If we were talking about 110V DC (which you probably aren't) you could built a DC-DC converter to turn the 110V into say 275V.
The output current would be 275/55 = 5A The input current would be 5 * 275/110 = 12.5A (if you ignore losses).
In practice the imput current is likely to be nearer 16A because DC-DC converters don't have 100% power efficiency.
If you are talking about AC the priciple is the same but the design is more complex. 110-220V converters are easy to obtain so achieving 4A (=220/55) is easy.
Are you serious? Or trolling for responses?

-- No.
So add a bridge rectifier and a capacitor up front. You want fries with that.
