    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

    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.
