When the rms voltages , and are measured respectively across the inductor L, the capacitor C and the resistor R in a series LCR circuit connected to an AC source, it is found that the ratio . If the rms voltage of the AC source is 100 V, then is close to :

Answer: (4)

Solution

Let , , . The inductive and capacitive voltages are in antiphase, so $ = Missing argument for \sqrt\sqrt{ +
