Question 52317
It's actually a Physics Equation... but I won't get in depth into that

Since this is purely math, think of the equation as {{{k=xy}}}

k = P
x = I
y = V
This equation is inversely proportional, when I increases, P is constant, V decreases
But since P can also change, when P increases, assuming V constant, I increases
When P increases, assuming I constant, V also increases


So basically, use it...
I am still unclear of what you are trying to ask me
