In Excel, or some other graphing program, from the data from Table 2.1 plot Current vs. Frequency. (15 points) The Current vs. Frequency graph should be nearly symmetrical about a particular frequency What frequency is it nearly symmetrical about, and why? (5 points) 2.

Explanation / Answer

fr = 1/(2*pi*sqrt(LC))

where L is the inductance and C = capacitance

substitute values of L and C as in table 2.2

fr_theoretic = 91.888 Hz

wr_theoretic = 2*pi*fr_theoretic = 577.35 rad/s

fr_experimental = 90 Hz

wr_experimental = 2*pi*fr_experimental = 565.49 rad/s
