An ac source of angular frequency \omega is fed across a resistor R and a capacitor C in series. The current flowing in the circuit found to be 'l ' now the frequency of the source is changed to \frac{\\omega}{3}, (maintaining the same voltage) the current in the circuit is found to be halved. What is the ratio of reactance to resistance at the original frequency?
