Transformer

1. Transformer Data

After getting 10 V~n pairs, you can fit the data using LINEST, and then get an expression like

V = mn + b,

which would help you to predict relationship between the output voltage and the number of coils.

2. 1.0V Transformer

The above equation can be rewritten as

,

you can use error propagation to get the uncertainty of n;

or fit the data as,

n = m' V + b',

then when V = 1.0 volt, the uncertainty of n can also be easily derived.
