Problem

In a series RLCRLC circuit connected to a constant rms voltage source, the inductive reactance equals the capacitive reactance at a particular frequency. The rms current at that frequency is (a) VrmsXL\dfrac{V_{\text{rms}}}{X_L} (b) VrmsR2+2XL2\dfrac{V_{\text{rms}}}{\sqrt{R^{2}+2X_L^{2}}} (c) VrmsR\dfrac{V_{\text{rms}}}{R} (d) Vrms∣XL−XC∣\dfrac{V_{\text{rms}}}{|X_L-X_C|}
