So the experimental data seem to suggest that at resonance (V

_{LC}=18 mV : min) the Voltage of the resistor is 834 mV. But the initial voltage given was measured 1.426 V (All Values rms).

Since at resonance it is Xim=0 so Xall=R shouldn't all the Voltage drop in the resistance, why is it less?

It's been bothering me for a while and by using the relevant equations I can't seem to figure out why does that happen. Why isn't even the total voltage V

^{2}=(V

_{R}

^{2}+V

_{LC}

^{2})

^{1/2}the same as the initial one. I also calculate bandwidth (R/L) wrong (by about 50%).

Did something went wrong in the experiment or do I not understand something?
