## When the rms voltages $V_{L},V_{C}$ and $V_{R}$ 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 $V_{L}:V_{C}:V_{R}=1:2:3$. If the rms voltage of the AC source is 100 V, then $V_{R}$ is close to :
