Answer #1

Data Display Default: A YO B X = 3177.86923, Yー-00965156794 || Polynomial Fit of Sheet1 D 0.8 0.4 0.2 0.0 2000 2000 4000 6000

This is the graph plotted using the data points, with frequency in X axis and Vout/Vin in Y axis.

The frequency at which Vout/Vin = 1/sqrt 2 = 3177.869 Hz

we know,

0.707 = 1/(1+(X_L²/2700²))^0.5

X_L= 2700.8155 ohm

From, X_L = 2 * 3.14 * f * L

we have L = X_L /2*3.14*f

L = 0.1353 H
