Hello
I have a doubt in the DC power calculations.
If i have a supply with 48V and delivers 5A no matter what load.
And i connect 5 ohm load to this.
if i use Power calculations like this:
V*I=48*5=240W
I*I*R=5*5*5=125W
(V*V)/R=48*48/5=460W.
Why there is difference in the power using these formulas?
