Is it possible to decrease the voltage without decreasing the current?
The discussion centers around the question of whether it is possible to decrease voltage without decreasing current, particularly in the context of electrical circuits and components. The scope includes theoretical considerations, practical applications, and specific scenarios involving DC-DC converters.
Participants do not reach a consensus on the initial question, with multiple competing views and a lack of clarity surrounding the context of the inquiry.
The discussion reveals limitations in the initial framing of the question, as well as assumptions about the application of electrical principles that remain unresolved.
This discussion may be of interest to individuals exploring electrical engineering concepts, particularly those related to voltage regulation and DC-DC converter applications.

phinds said:yes, by decreasing the load.
Your question out of context really doesn't make any sense.
neeraj kaira said:I know this any other formula for it

neeraj kaira said:Haha again ohm's law
neeraj kaira said: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 .
berkeman said: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.
