Answer 2

yeah, that doesn't help. i have a specific issue. my lab manual says to do a curve fit with a defined function, but it's not working.

Answer 3

To find the load resistance maximizing the power transferred to the load, you will use the curve fit feature of LoggerPro. In the upper tool bar menu click the Analyze tab and choose Curve Fit. In the Curve Fit window click the Define Function button. This will open a new User Defined Function window where in the “f(x) =” field you need to type in function of the same format as derived in eqn. 5. For example: (Ax/(b+x)^2. As shown above for simplification you can use parameter A to represent VS2 and parameter B to represent the internal resistance of the voltage source, RS .

Answer 4

i have columns for I, V, and Rload, but when i try to do the Ax blah blah, it doesn't work. when i plug in values, it doesn't work. i'm not sure how to do this.
