Building a Transformer

1. The inline questions in Warm-up Section (5.1) is asking about the induced signal, not the signal from the function generator.

2. Number of Coils when V = 1.0V:

Uncertainty of n when V = 1.0V:

1st Way (suggested):

If you fit the data, using LINEST, as

,

then since V = 1.0V is a fixed value, we have

,

and

,

where δm and δb are the uncertainties which can be gotten from the LINEST results.

2nd Way:

If you fit the data, using LINEST, as

,

then

,

so

,

where δm and δb are the uncertainties which can be gotten from the LINEST results.

Note: The m's and b's in the two ways are not the same!
