# Math Help - graphical method?

1. ## graphical method?

hey i cant think of a simple answer to this. im looking for an obvious anwswer

t=switching time
V= applied voltage
A=constant
B=constant

the formula:

t=A/(V^2-B)

how can I extract the constants A and B by a simple graphical method from the data

2. I can't give you an "obvious" answer ... but I do have an "answer".

solving for $V^2$ ...

$V^2 = A\left(\frac{1}{t}\right) + B$

if you graph $\frac{1}{t}$ vs. $V^2$ as x vs. y, you should get a linear graph.

A will be the slope of the graph

B will be the y-intercept.
