An a.c. source of angular frequency \(\omega\) is connected across a resistor R and a capacitor C in series. The current is observed as I. Now the frequency of the source is changed to \(\omega /4\), (keeping the voltage unchanged) the current is found to be I/3. The ratio of resistance to reactance at frequency \(\omega\) is
