So in physics, one smart teacher told me,
V = IR
I = V / R
but it is not always true, because
P = VI and each power supplying device (such as battery) has a "maximum power" it can provide. So
I = V / R is true as long as
P = VI doesn't exceed the maximum power the battery can supply.
So will old style AA batteries, Alkaline AA batteries, and NiMH, rechargeable alkaline, Lithium AA (Energizer) all have similar MAXIMUM POWER? I am suspecting my Mario Kart Remote (fit in a wheel) for playing Mario Kart Wii not behave the same when using different batteries. The best seems to be the Duracell Ultra Alkaline, and then the Duracell rechargeable pack for Wii remote (2.4V only) works also flawlessly (but can it be, because it is very snug?)
Otherwise, sometimes I turn left and do a drifting and the console thinks that I am drifting right... so it does seem that different batteries have different outcome... and I am suspecting can the Wii need more power than some batteries can provide? and so how do they work really?
(I cannot add a tag for
ohm's law because I am new. Can somebody add it for me?)
