yes, by decreasing the load.

Your question out of context really doesn't make any sense.

Yes.

V=IR.

Voltage=current X resistance

Look, you are wasting people's time. Please stop doing that.

State your full question and application clearly, or this thread will be deleted.

Turns out his question was about DC-DC converters. From a PM exchange:

Ok let me tell you...i m thinking to make a charger which output should be 5v 1.5 - 2 A
And i'm getting 18 v after stepping down the voltage so i want ti decrease the voltage to 5volts keeping current high.
Hope you will get this .

You use a "Buck" DC-DC converter to lower the voltage with high efficiency:

They are available off-the-shelf, or you can build your own with a Buck DC-DC converter IC, an inductor, a diode, and a capacitor.
