An a.c. source of angular frequency ω is fed across a resistor R and a capacitor C in series. The current registered is I. If you the frequency of source is changed to ω/3, maintaining the same voltage, current in the circuits is found to be halved. Caculate the ratio of reactance to resistance at the original frequency ω.
