The heated bed is 24 volts. I would like to know how much current is going to the bed of a 12volt heated bed vs a 24 volt bed. I do not use ohms law offten, but is it power/voltage equals current? Or is there a better formula Thanks Sent from my SM-S920L using Tapatalk

Why don't you tell us what you are actually trying to do before you make a damaging or even fatal mistake with electricity ?

Are you trying to convert supplies or what?

Nope, no converting or moding, just wondering. Oh, its a 250 wat psu.

My friend has the 12volt version and mine is the 24volt. We just want to figure out the current differences haha
