We made a RLC circuit in the lab and took some values of R and LC Voltage while we changed the frequency. So the experimental data seem to suggest that at resonance (VLC=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 V2=(VR2+VLC2)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?
