In Excel, or some other graphing program, from the data from Table 2.1 plo Frequency The Current vs. Frequency graph should be symmetrical about a particularf frequency is it symmetrical about, and why? 2.Explanation / Answer
For First Table we will use the formula i(R) = V(R) /R thus starting from f = 10 Hz to f =150 Hz
answer will be 0.0201A,0.04A,0.06A,0.0815A,0.1026A,0.1218A,0.1362A,0.1443A,0.145A,0.1416A,0.135A,0.1277A,0.1196A,0.1127A and 0.106 A
now we can see that maximum value of current is comming at f=90Hz so resonating frequecy should be 90Hz but we also know that formula for resonating frequency is f = square root of (1/{4(pi)^2 LC} = 91.937Hz
